Dozen ways to skin a cat GK22, Listen to jaliso and go clean. Stop all the additives and high price recommendations... learn to read npk and elemental formulas on the back. Then remember these guys are trying to make loot, and fudge numbers sometimes with inferior products when salt suppliers run out... on occasion....
That being said, lol
simple one or two part veg/bloom, Cheap ones can be excellent too...
a micro,
epsom salts, Costco has them cheap in 6lb boxes
quality booster. I use cch2o booster in all growing medias. Cleeeen and boosts! (not cheap)
brew a proper tea once a week.
Lastly, a quality non
cal-mag product "only" if necessary when dealing with calcium whores... Ive had "bad"
botanicare cal-mag several times now.
Calimagic or magicali are solid.
Heres a kicker most novice growers will disagree with. Calcium isnt needed in excess like most people think for coco. Most grower foods have it in excess already, plus we are stacking in micro too, then tea also has a small amt. AND tap water has it, if not using r.o...
I use r.o water and still never add any
cal-mag products. What happens is, coco attracts calcium and binds it to the media if you aren't watering PROPERLY... .
knowledge is 2lbs+ per light. Ya dig....
