So my carbon filter was not breathing properly.   I had to change the filter out.  I always keep my environment no higher then 78 degrees.  It had gotten up to 84 degrees, due to me having to leave do my unexpected work trip.  Thank god I caught it after a few days and corrected it.   Just discolored the leaves some.

What exactly do you mean by heat issue? Djd AC fail and it went hot? What temperature is too hot?

Update on my 4x4 and 2x2 tents. The 4x4 has strawberry banana, a purple punch (in a 2 gallon pot for an experiment), and Skywalker Haze. The 2x2 has gorilla cookies. Day 70 for all. Had some heat issues, (due to an unexpected work trip) but corrected them.
