what up peeps. jacks back.
Ran out of jacks a while back and decided I would make the move to all raw salts. My plants did not like this, and so I am going back to a modified jacks formula, which was working great for me before.
I ordered the following from JR peters:
jacks classic blossom booster 10-30-20
jacks cal nitrate 15-0-0
jacks professional hydro formula 5-12-26
MOST
pH adjuster
I also have, which I ordered from cutomhydronutrients (those guys are the best):
Magnesium nitrate
0-0-50 sulfate of potash
MKP
MAP
and from the local pharmacy a 6lb bag of epsom salts.
So I got the MOST. It does not look the same as the STEM, even though the GA's are the same I think. This time, it came with a descriptive sheet for each product, and I read the MOST page.
Since I started on jacks, I have gone from adding .1 MOST to .2 MOST more recently. And here lies my problem I believe (for starters). The sheet recommends that if using a 15% nitrogen fertilizer, you should only add 2oz MOST per 25 lb bag. That's roughly .005 grams per gallon. A far cry from my values.
Now I have done quite a bit of reading up on other successful growers and their formulas, and it seems to me I have found a ratio that will work very well, or so I think.
I will be running this (all in per gallon values):
2.5 grams hydro
2.13 cal nitrate
.2 Cacl2
.095 MKP
.55 k2so4
.71 epsom salts
.005 MOST
which will give me 120-40-210-120-60 and the sulfur will be at 103.
first I will add the hydro, MKP, MOST, and K2so4 in a 5 gallon bucket of warm water and mix until dissolved. I will add this to a full res of RO water, and MIX well.
then I will add the epsom salts the same way
finally the CaNO3 and CaCl2 in the same way.
this is per manufacturers directions. So much fucking around... trying to be a mad scientist. its not working so I am gonna follow some directions (not all) from the people who are celebrating their 65th anniversary in fert blending.
I have seedlings that just popped. they are FPOG crosses. FPOG x kosher kush, FPOG x WiFi, and FPOG x my Colombian landrace. I will start a journal on them which I will link here. I will use this formula (25% strength for seedlings, 50% when they are 4-6" tall, and full strength at 12" until week 4 of flower, when I will change the formula to drop the N slightly and boost P and K.
My goal is to have all the plants thriving. No yellowing, no toxicities, no deficiencies, all the way through.
the medium will be 50/50 big and chunky perlite and
botanicare washed sterile coco in a bag.
