Uhoh!! Some yellowing! Need input..

so today I opened up my box and I immediately noticed that the bottom fan leaves are yellowing. A few days back I added some nutes. Stronger dose than norm. 8-8-8. It as also been pretty warm out making my box hit 88F for the 2nd day in a row. Raised the lights a little bit and my reflector to help drop heat near the plants and vent to the to exhaust. I have the plant a nice watering of filtered water to help flush or deluite any possible bite burn. What could be the problem? All other leaves are healthy looking. Few days of almost 90F? Nute burn? I also heard the bottom leaves usually yellow out. I might have to change my light schedule so they come on during cooler hours of the day/night.

There's a trick to keeping it from doing that. I haven't mastered it yet. All my plants have two yellow leaves. Once it explodes in flower, you won't care. They'll still be yellow while everything else is brilliant green.

Cut them off after you harvest. That's about as much trouble as they'll give you.

No worries.

Heat still not good? I know it's high. Only a couple months before I can justify using the AC in the band room (where my box is) but outside temps should drop down to mid 60-70sF. Usually my box is a nice 79-82F.

Anyone else have some input? Didn't get to check them tonight after working an 11 hour day. I know temps would have been fine today.

Doing much better.
