hey thaniel, the yelloowing happening on your plants, is it happening more directly under the light? mine were doing this, yellowing at the tops of the plants but wasnt heat stress, in one of my rooms its 11x11 with 9kw, and the ones directly under the lights would stay shorter more compact but also get yellowish coloring at the tops on the leaves, this imo was caused by the light, just plain and simple too much light, i had the lights about 14" away from the tops maybe less, but thereis no heat probs cuz the plants didnt burn at all, i csan lower the temps down to 15*C if i wanted to, these a/c's are pretty good. so in short to solve my problem i just raised the lights about 6" and the plants got greener.
my thaughts were either A) light bleaching or B) plants were growing so fast that it would run out of ferts before the other ones, but i think option A is the right one.
ive read that at 75w/sqr ft is max recomended light for your plants, at 75w/sqr ft and above if the lights are too close this creates light bleaching, if i had more room i would of spread out the lights, but i got 10 ballasts and relays so i had no coice but to split it in 2 rooms with 10 lights in each room, but i could only fit 9 in the 11x11 room. if i thaught that the extra lights wouldn yield me more then i would drop them to 6 lights, but i know the extra 3 lights is atleast an extra 5-6lbs so im leaving them and gonna work around it and try and fix my rh prob
