withou knowing more it sounds like you need more ventilation. Where is the heat coming from, that light isn't putting out that much heat.

Be patient. Other people have problems in the grow room to deal with too :jointsmile: Might not have time to help out... or they're just plain busy :smokebong:

Found this for you:

Heat is the problem, sorry to break it to ya, you HAVE to deal with it, or consider moving your grow outdoors.
High temps exacerbate other problems, and yes, the pale patches are likely a secondary effect of the heat.
Chlorophyll starts to break down in the mid 90s. Enzymatic processes grind to a halt. No amount of food, water, or foliars will solve the problem if the plant lacks the enzymes to assimilate nutrients.

I read somewhere that the perfect "lights on" temp is 77.2...The same person said that THC production starts to slowly diminish at temps above 80 degrees without CO2,and much more noticeably at temps above 85 degrees...
Temps 90 degrees and above without heavy CO2 can be stressful enough to cause a plant to hermie and would also seriously affect the plants THC production...

The normal amount of CO2 in our outdoor atmosphere is 0.03-0.04% CO2...

Well, you certainly aren't going to get the MOST out of this grow if you can't get the temps down, but if you have females you'll still get buds... They'll just be fluffy & airy, and probably not as potent as they could be.
Circulation is good, but you need some fans pulling fresh cool air into the grow space and some fans pulling hot air out.. If you can do that, your temps will drop into the high 70's- low 80's and your plants will love you for it. :)
