Is it just the jacks pro hydro and the pro cal nitrate? Thanks!RO. I don't even pH. I used to have to pH with MB. This is my first full run with jack's in flower, and the plants are a little greener than I would like, but this strain came out looking essentially the same last time but was even lighter in color with the MB. Other than color the nugs are essentially the same.
No additives, except maybe some molasses late in flower. I have played with pk boosts in past grows, powder KB, MOAB, but I seem to get the best results keeping things more consistent and at a low EC.
If you are serious about growing, drop the $150 on 25# bags and you won't regret it.
