Hey capitulator I have a few questions if it wouldn't be too much trouble. I am switching from soil to home made Aeroflo units. Would your Jack's formula be okay for Aeroponics without any medium? If so is there any way you could recap what you purchase, the actual amounts of each for the various stages and if and which of your bennies could be used. I read through all the post, but you changed it up so much that I lost track. I am not as smart as a lot of you guys lol. I have only ever grown with super soil mix, this transition seems like a pain in the ass.

I heard Yucca Extract can get rid of clogging problems~ Good idea to strain the tea anyway in case there are any clumps in the developing micos


Starting my first full grow based on this formula tonight~ see you guys in a few months with questions and comments~

yeah add MAP if you want to make your own MOAB.

Although the formula I detailed in the beginning of this thread is working just great, I realized that adding Protekt is fucking with my K. Duh!

So I tweaked the formula a little and have been using it on a newer batch of plants. This is for veg and weeks 1-4 of bloom.

Jacks hydro: 2.7 grams/gal
CaNo3: 2.8 grams/gal
MKP: 0.2 grams per gallon
MOST: .005 grams per gallon
K2SO4 0-0-50 : 0.5 grams per gallon
CaCl2: .2 grams/gal
Silica: 5ml/ gal.
Epsom salts: 0.5 grams/gal

this gives me something like:

150N
49 P
258K
58 Mg
150 Ca
97 S

I would run this at 80% until they got in to the flower room with more light, then I would run as normal. I will be trying this in a few days on the colombian and the white fire I have ready to transplant from cutting within the next day or two.

Greetings Cap
I have recently switched over to using Jacks pro and CaNO3, in a 1 to .67 -jacks pro/CaNo3 ratio.
Throughout veg everything looked fantastic- beyond amazing and healthy. Now 3 weeks into flower it is clear I need to beef up the formula. Dug around here and discovered your recipe of which I will be implementing immediately. As this recipe is several years old, I wanted to check in and see how it's been going for you, and if you have changed and aspects of it for the better. Also looking for clarification on the Silica source...were you using botanicare silica blast?

Much appreciation!

Is no one else burning the hell out of their plants at such a high ec? I can't go anything above 1.5g/gal of each without frying the ladies. I don't get it.

1.5g ea, and 1g epsom gets me right around 680ppm on a .7 scale with 0ppm RO water. Feeding 4 times/day in flower, they are in coco and loving it. Anything higher and leaves turn CRISPY!

If anyone can shed some light that would be awesome[/QUOT
I think your supposed to use 3 grams jacks 1.8g calnitrate to 1g Epson.....but whatever formula you use keep your ratios the same(that's whats important) and dilute to a more tolerable ppm(450-500). for example, if you have a 55g rez, try mixing the salts for a 35g mix.
