im using only cocogro. its 5 of them. i havent gave them any nutes until today. i made a gallon of ph'd ro water which had nutes from the GH Flora series, recommended amount was 1ml florogro, 2ml floramicro, and 1ml florabloom. i downsized to about 25% which made it .25/.5/.25 ml(that i actually poured in the gallon). then i gave each a styrofoam cup full. temps usually around 76-84f, sometimes extreme heat can push up to 90f. i have a intake fan and a exhaust fan. both are probably about 6 inches. i have 4 more 120mm pc fans circulating the air around the seedlings. the lighting is 1000w equivalent cfl bulbs.each 100w.10 bulbs 6 2700k and 4 is 6500k.i have the lighting no more than a foot above them , im scared of lowering it because they get pretty hot.
