Ok. I have 6 phantom commercial lights. Spread across a 14x15 area. The room is actually 14x19 but plants only using above area an lights setup to not pass 15ft... this is giving a 5x5 each light with little missing area on sides. I have inline setup to cool room with outside air. Temps are mid 70s an room is alittle dry (no humidity check but leafs alittle dry feeling). They eat every 3 days. 2 gallons each with gh nutes. Been using gh for 4 yrs so i know its not my food. Been supplimenting some extra cal-mag just in case. The plants are eating, they are growing new nodes but the leafs an general look do not seem happy. I started them under 1150w and turned them down to 1000w for 5 days now an still seem stressed. I just turned my back 4 lights down again to 750/800w (whatever 75% equates to). Dont wanna start flower until i see open leafs uptop plants. I can say which is wierd i think anyways but the under growth of plants are growing great Top growth, well look at the pics... this is why i was turning lights down more. Oh yeah an lights are atleast 4ft from canopy.
