Jacks recipe for light dep?

I'm trying to implement a recipe using jacks 321 with supplements to get some dense, heavy yields.

Currently I have around 90 plants (between 3-7ft) in 15-20 gallon pots, with a mix of Ocean Forest and Happy Frog soil.

Having read a lot of good info on here i'm going to switch from bottled nutes (AN) to a jacks formula and mix myself as i'm on a tight budget.

So far I have 50lbs of jacks 20-20-20 , 50lbs of jacks bloom boost 10-30-20 and 50lbs of calcium nitrate. I am using well water which is at around 200ppm. I would like to revive half of the plants that we only bought and transplanted a week ago but still have wilting leaves, and then flip as soon as they are healthy.

So my base recipe so far is:
3.6grams/gallon mix between 20-20-20 and 10-30-20
2.4grams/gallon cal nit
1.2grams/gallon epsom

and optional extras:
0.25grams/gallon potassium silicate
0.25grams/gallon ammonium sulfate or phosphate

and then a weekly tea drench of:
2grams/gallon recharge
2grams/gallon sea-90

Cal-nit will go down mid flower to 1.8 grams and Epsom increased mid flower to 1.8 grams. Salt leaching solution in flush.

Would this recipe be a good starting point? I'm looking for big weight and dense, flavorful buds. Do I need anything else to achieve that as I've heard the only problem with jacks is nodal spacing and density loss.

Also what about adding hydrolized whey protein/fulvic acid/sugars/molasses/sweet raw/sea kelp etc..?

sounds like you have a good idea what you're doing. 3/2 ratio for the base & calcinit sounds right. if you have potassium silicate on hand you should use definitely use it unless you think it'll bump your ph too high. i don't believe it'll effect ppm's much at all.

the recharge you're using has fulvic acid, molasses, and kelp. perhaps doing a weekly foliar of kelp, recharge, jumpstart, and biocozyme is an option.

thought?
 
Thanks i'm just confused with all the "extras" needed to push for that dense, tasty, weighty nug. What does the jumpstart and biocozyme do? I was trying to stay clear of liquid nutrients/supplements and just do powder throughout as it seems to be the most cost efficient.

I use and have been using jacks for years. The jacks hydro 5-12-26 base, calcium nitrate and magnesium sulfate. I start right out the gate at 650 ppm on a .5 scale (1.3ec). Ive used a few of the jacks products but always end up back to this. I go up a bit during mid flower and I keep the ratio the same throughout. I get great results. Only thing I add is silica and sometimes potassium sulfate as a booster. That's it. I buy jacks from Amazon 2, 25 pound bags of each for $270 and that's enough nutes to last me a few years.

Happy growing.
