Just over a month in veg feeding GH floral line with cal mag/floral blend/SI/rapid start/ running around 550 just bumping it up slowly over a few days now at 700 -740 in a RDWC ,RO water, leafs are light green now there curled up and some are showing spots
I am no expert, however i have had the pleasure of dealing with a "hot" environment. The curled leaf edges seem to indicate high temps, and probably low RH. I could be wrong; my apologies if I am. I will leave the nuit defs to the more experienced growers. The knee-jerk stmt. is always cal-mag. Personally, i would wait to hear from some of the OG's. :mushtache:
It stays 71-78 at most in here it’s in my back room in the house, humidity stays around 48-58
Water temps are 73-78
I got my led light 1-1/2 to 2 foot above tops also a fan on 18/6 with them
