Ok so I cranked the humidifier back up to high, got to about 60% humidity, and moved some stuff around and got the light back to about 32" up. I know theres no set guidelines, but ive read so much conflicting info, ive seen great grows with the same light at 42" and some at 20". I have a small heater in the room keeping temps during the day from about 75-84 and down to maybe 70 with the light off. I do have a fan moving air and I know the powdery residue isnt mold or mildew. Also been feeding them distilled water with a little tap to bring PH up around 6. I fed almost a gallon to the 5 plants today after not watering yesterday and added "regular strength" week 1 nutes which were 11.5ml add.27, 2ml grow A, 2ml grow B, 2ml root starter, and 2ml calimagic. I was hesitant to add so much add.27 but we'll see how they like it.
Been learning a ton and I already want to start grow 2 since ive learned so much so far! Thanks for all the help and advice everyone:Cheers:
