I can not seem to find what is causing this as so many people reference so many things. the temps are not going above 78 with the lights on and below 62 with them off. I do have a humidity issue with the lights off even with my intake and exhaust running 24 hours. I was thinking heat at first but it is only one or two water leaves doing it and its not at the very top of the plant. overall the plants are doing good and looking healthy I just noticed this last night when the lights came on a day after feeding. I don't know if it is related but about a hour after feeding that night the leaves were all pointing up at the light even the bottom leaves. any help is appreciated.

Leaf curling up like that usually means light to close to leaves they curl up in aid to catch more wind to cool down.

What's the humidity level at? Also take some pictures in natural light so ppl can see what's going on.
during the dark period the humidity has been going up to almost 70% RH sometime. usually mid 50's to low 60's though. it has been raining here though. ill snap some photos when the lights turn on tonight but I can not move them out of the tent so ill have to do before the hps fully warms up. I bought a digital ph pen today so I can be sure of my ph level of the water im putting in no more guessing with the drops and color chart. also the guy at the hydro store gave me a bottle of "enzymes complete". it is supposed to clean out the soil. I aint never heard of it so ill have to research it before using it. I forgot to mention earlier that im using ffof soil and the GO box for nutes. i only waer with RO water also. I have not flushed the plants ever really as i did not think it was required with organics.
