Hello guys, newbie here and pretty confused hoping y'all can answer some of my questions. Is 0.5 per gallon the right dosage for COCO A (it's the one given in the back of the bottle) or do you use more oz per gallon and why? How much gallons of water should I be using for 30 plants in 20 gallons? I currently use 100 gallons of water so that would be 50 oz of COCO A Do you really need to use rhizotonic all 8 weeks of flowering? I find it pretty pointless to use it on week 7 & 8 when you're 2 weeks from harvest why do you need to continue giving roots growth?
