 Veg
 
   Week-------1--------2
   GROW----10------12
   BLOOM----3--------3
   Micro-------5-------6
 
Bloom

   Week-----1-----2-----3----4----5-----6----7
   Grow-----2.5---3-----3----4----4-----4----4
   Bloom---10----12---14---16---16---16---16
   Micro-----6-----6-----7----8----8-----8----8
   Ml per Gallon
 
You should Leach your system between the veg and the flower cycle or your plants may stretch. This is also designed for a 9 week strain so if you have a 7 week strain only go to 5 weeks then leach. As you can see weeks 5-6 and 7 are the same anyways
 
 


Pacific Northwest Garden Supply's GH Recipe

 

This is a feeding program for active hydroponic systems. All measures are in millilitres (ml)

Babies:
                   Micro            Gro              Bloom             Vitamax             Super Oxy
                     2.5               5                   2.5                   10                       0

Teens

                   Micro            Gro              Bloom             Vitamax             Super Oxy
Week 1           5                  10                 3                     10                        0
Week 2           6                  12                 3                     10                       1.5
        - This is the highest concentration that you would ever use during the grow cycle, even if you grow for 2 more weeks.

Adults
                   Micro            Gro              Bloom             Vitamax             Super Oxy
Week 1          6                  2.5                10                     0                       1.5

Week 4          8                  4                   16                     5                       1.5
Week 5          8                  4                   16                     5                       1.5
Week 6          8                  4                   16                     5                       1.5
Week 7          8                  4                   16                     5                       1.5
 

For dirt farmers, this is an alternating program where you water once and then you feed once. Don't forget to flush.
 
 
 


BD97's current recipe

:::clones into 1in. pretreated at 5.3 ph, and Vit. B1in RW cubes, after 3 days remove humd. dome and water twice a day with equal amounts of Gen Hydro-----PPM@ 5 --5.8 PH Let drain very well, no water
sitting in the bottom of trays. If anything, tip trays so that clones do not fall out and let drain through a hole in bottom of one corner of tray. Let sit that way for 3 to 5 min. { look at your watch!}----Roots in 7 days!!
 

                -------------------------------micro-------bloom--------grow-----in that order!

                --rooted clones 1wk. =       15------------15------------15------PPM=7
                ---------veg---------2wk. =  20------------10------------30------PPM=9

                ---------bud---------1wk. =  15-------------30-----------15------PPM=10
                ----------------------3wk.=   20-------------30-----------10------PPM=10
                - bloosom blood added at this time
                ----------------------6wk.=  10--------------30-----------10------PPM=10
 
                ------flush with clearing solution last 12 days of an 8 wk
                bud!-------epson salts 1.5 tsp. per 5 gal.--------PPM would be at 10
                to 12 or at what ever your girls can handle. Just use those
                ratio`s.-------All measurments in ml per 5 gal bucket. Tops pinched
                back on day 10 of veg, RO water if possible! PH at 5.8--------Yeild
                should be in the 1.5 to 2 oz a 14in to 16in  plant range, if not get a
                better strain!----LOL!!-----Oh ya, thats in Aero by the way-----Yea
                haaa!!!! as if it was in dirt,{ rub rub, wink wink! }



and another from BD97:

--------1994 recipe-----

               :::::OK here goes!!!:::::

                -----All are in ml per 5 gal bucket-----oxymoreon?

                --rooted clones = 5ml micro, 5ml bloom, 5ml grow

                2nd.wk of grow= 10ml micro,4ml bloom,8ml grow

                4th wk + on = 15ml micro,8ml bloom,30ml grow

                ---12+12, = 15ml micro, 15ml bloom, 15ml grow

                2nd wk. = 15 ml micro, 30 ml bloom, 15 grow

                4th wk. = 8ml micro, 40ml bloom, 15ml grow

                7th wk.+ on = 0ml micro, 60ml bloom, 15ml grow

                ----use clearing solution for the last 12 days

                

                Looking back with the 0 amount of micro in the end. It should pose no
                problems to the girls with not having any micro nutr. for the last wk
                of nutrs. before clearing!

                Will send the one that i`m going to use a little  later
 



Orchid Man's Salt Fert Recipe & Notes

 
Here are some of Orchid Man's notes on salt ferts. With his help I plan to make this a faily complete guide to using them. Any comments, advice, and/or help would be appreciated and can be emailed to vic_high@hotmail.com

    CA(NO3)2 calcium nitrate veg= 1.5 gram/liter flower: 2.0 gr/l
    KNO3 Potassium nitrate veg= .7 gram/liter flower: 0
    KH2PO4 Monopotassium phosphate .5 gram/l Flower: 0.5 gram/liter
    MgSO4 Magnesium sulfate veg= .8 gr/liter flower: 0.8
    Trace element 0.1 gr/l flower: 0.1
 

    Always mix the Nutes in the order shown above in a full tub of water.
    Mix the calcium Nitrate well before adding the others. If you see a overfeeding look
    on the top leaves, lower the calcium Nitrate Rinse the medium once or twice a week. the recipe depend of the type
    of water used too. It is a base formula to start with.
 

    In the flowering period , in the last month, start lowering the calcium nitrate so that on
    the last 2 weeks you would be at 0.5 gr/liter or less.

    I'LL post later on the subject . Frenchie.

    Geeezz i like answers like this. This is the kind of discussions i am looking for. I wish i was as diplomat and
    fine writer like you. But unfortunatly i am not :)I am a rough, short fused ,undiplomatic and grouchy old fart.
    maybe reading messages like yours and ~shabang~ will teach me how to act properly here. I am working on it :)

    You got it right bro. If i would be newbie, i would not start with salt fert. It is simply too complicated. But when i
    did start growing many years ago, GH wasn't on the market yet,so i have had to learn to work with salt fert.
    And since then i can compare the difference between both type of fert. from seeing other crop of my friends who
    are using GH. And they keep asking me how to get the harsh taste out of their weed. But they wouldn't switch for
    salts, so i sure don't expect to convert everyone here :)

    I never did work with organic fert, since i wouldn't have a clue about what is going on in the substract when i
    would be adding some chem fert like GH. Impossible to know because of the large amount of mineral in organic
    fert, combine with Chemical fert, end up being a brew too hard to control. I don't like to not knowing what is going
    with my fertilization.

    The only thing i can say is as long as urea nitrate is used, it will be very hard to get a smooth taste with the
    finished product. urea Nitrate seem to stick forever in the plant and is so hard to wash out. My friend have tried
    to rinse with water only for 2 weeks prior harvesting and they still have this harsh taste, and i don't. I don't cure
    neither. It is on the market 5 days after harvesting with no harsh taste and very sweet.

    Those who are using organic fert should not add micronutrient before half way thru the growing process.
    It is less harmfull to lack a bit of micronutrient than to have too much of them. Many peoples are overfeeding,
    wich create super problems. Don't forget that the guys selling the product wants you to use as much as possible ,
    they want to make money. I suggest to those who want to do a test, to have a few plants with half the fert you are
    using for the other plants and see for yourself.

    Can you beleive i have been fertilizing my KONG weed only twice a week so far? and do they ever grow fast
    these guys.
    You can see when your plant is ready for another shot of fert because of the top leaves getting paler green.

    The main thing is better less fert than too much. when nutrient start to lock up it is very hard to know what to use
    to undo this since we can't know exactly what is locked up with what. if you don't overfertilize you won't get fert
    lock up. Micronutrient are the most touchy part about fertilizing. It has to do with the kind of water you are
    using.

    Other thing that growers should know is the amount of oxygen the roots system get. OK ,P2O5 has 5 atoms of
    oxygen for 2 phosphorus,but as soon as you balance your ph the O5 is reacting and oxydize turning iron to rust
    and zn to who knows what, instead of giving the oxygen to the roots.

    This is why it is an incredible mess to describe.

    If anyone wants to learn more about all of this go to this url . EVERYTHING is there. Full course on nutrient and
    all.:http://res.agr.ca/harrow/bk/toma99.htm

    Doesn't matter if they talk about tomatoes, super site to learn about ferts. read the section about Soil reaction (ph)
    they know what they are talking about. Will save me a lot of typing :) i hope this help Bye for now and thanx for
    the input. I needed that :)
 
 

                            Anyone using Salt fert?
                            Posted by Frenchie on December 25, 1998 at 12:54:39
 
    I would give some tricks about salt fert only if there are someone using this kind of fertilizer right now,or intend
    too. It would be useless for me to post on salt fert if nobody plan to use it. If there is someone who is starting
    with salt fert, let me say this: don't be surprise to see larger leaves and paler as well. Don't overuse Nitrate to try
    to get the same dark green as GH would do, the leaves are very happy with this paller green. The plant will grow
    much faster than with other type of fert so you will have to watch closely cause it will go fast and you will have
    to keep track of the calcium Nitrate ,because it is the only Composant of all the familly to watch for. Calcium
    Nitrate does wonder but can kill the plant too if missused. The other composants will stay the same ratio during
    all the plant life, only the amount will vary.
    You don't have to use K2SO4 ,instead raise the KH2PO4 and KN03, slightly. Overfeeding is easily recognised
    with salt Fert because of the rapidity of this type of ferts to work.
    If you start seeing Nitrate overfert, Rinse the medium and let the plant drink the water. you won't burn them
    unless you fertilize when the medium is too dry. Over feeding with P or K is very rare with salt fert . The only
    one to watch for will be the Micro nute, don't overuse it, and the Calcium Nitrate. If i get some peoples interested
    on this subject, i will post later on the WONDER of Calcium Nitrate and all the Good things this stuff can do to
    your plant. Friendly yours Frenchie ... O.M. is gonne

    I hand water ,in Promix#4, i use a garbage container about 80 liter. One is filled with water and Monophosphate
    potassium KH2PO4 (one small plastic fert cup) Micro nutes and one tea spoon of MgSO4 (half a fert
    cup)depending if the water in your locality is hard or soft. hard water contain enough Magnesium , Calcium and
    sulfates to do the job. I use this Mix for Washing twice a week. If the promix is too dry, use plain water ,wait 2
    hours then fertilize.
    The other container is filled with the full recipe.Smaller the plant ,more water i use (to let the medium get dry
    ,good for the roots). The solution has to be as fresh as possible, not cold.When you fill up the reservoirs, make
    sure to make as much bubbling with the hose to oxygenate the water. At the rate the plants will drink,you should
    never have some old solution. When flowering,i use half and half (both reservoir)so i can play with the Nitrates.
    Fresh Promix should keep his PH in good shape aqll the way. Overwatering degrade the peatmoss . With salt ferts
    to tell you the thruth, the last time i did check the PH was 15 years ago and was neutral so i never checked it again
    since. The only way i can see if something goes wrong is by looking at the leaves and the way they grow. The
    growth will be very consistant, so if something goes wrong,you can see it. The only fert to watch is like i said
    calcium Nitrate, this stuff on an very thirsty (dry) will kill it in 4 hours. If you see the tip of the leaves turning
    brown, flush with water and let it dry and pray.
    I 'll stop here for now. waiting for questions.
 
 

                  KH2PO4 is monopotassium phosphate

                          In Reply to Re: Testing ferts Precisions posted by Orchid man.
 
    calling it monophosphate potassium may get some strange looks across the counter, better to call it
    monopotassium phosphate. True there is only one phosphorus atom per molecule and thus "mono = one" says
    monophosphate is fine, the ambiguity in the compound is the number of potassium atoms present as the
    phosphate can attract one, two or three potassiums, thus it is better to specify "monopotassium phosphate" and
    there'll be no ambiguity as to the number of potassium atoms per phoshate compound.

    Using a heater would do, just make sure you make some Bubling each day to keep the oxygen level nice. if you go
    with a Pump system,then the water get oxyganeted with the flow and spraying. One can for example: make a new
    solution, go with it for one day, if half the solution is left in the reservoir,add water for the next day. Then discard
    waht's left ,to get a fresh solution on the third day. The best is to be able to use the solution as quickly as possible
    but i sometime use the same solution for up to 4 days if i don't have enough plants and too much solution.

    These kong plants drink like creasy ,up to 5 liter each a day. They are 4 feet high without the pot, very branchy.

    After stretching wich was minimal the Kong went down to a more normal level as water intake.... When one plant
    is processing at least one liter of fluid a day, you can say ...it is in shape and growing. 2 liter a day, you're in
    business. :)
