Nutes for 32 plants with 4 k HPS and 200 gallon REZ

Hello All,

I am planning a grow area in 12 by 14 room which will hold bloom,veg and clone rooms.

Keep in Mind its a sealed setup that i am planning with co2 burner and A/c with De/humidifies.
I want to use botanicare pure blend as base nutes and add cal mag, silica blast (Cell wall) hydroguard (roots)

Also want to use terpinator for flowering> do u think that i shud add Botanicares hydroplex or tea blend instead?

Now I am leaning towards this combo:

Botanicare Pure blend pro - grow and bloom with 6 weeks veg and 8 weeks flower
according to nutrient calculator on their website with bi weekly rez changes as i am using rdwc.

Grow 3 gallon
bloom 4 gallon

Additives- On their schedule they tell u to use each and every additives with each feed> so with that calkculation

Calmag plus - 2 Gallon

Hydroguard- 2 gallon

Liquid Karma -2 gallon

Silica Blast - 2 gallon

Terpinatior 2 gallon --- during week 2 to week 6 flowering

As You can see except of terpinator and base nutes I am not sure if I shud really buy 2 gallons of additives. also keep in mind that the country where i will gro doesnt have a hydro shop or hydro store therefore absolutely pivotal that i land in there with the right amount of nutes.I wud also be very appreciative if anyone can point pout the purpose fo each additives and any cheaper subsitute that oi can buy

lastly, is it possible to guide me toward more cheaper nutes?

I like botanicare they say it natural and organic.and that it can't be use in hydro. I'm using dyna gro but I found that it's very just chemical fertilizer 1 bottle 17 different mineral .I try to mix it with humex and fulvex acid and I use hydroguard I was thinking finishing the last 4 week with botanicare instead of dynagro just for testing maybe it will help me a bit
