MEDICAL CANNABIS GROW LOG UPDATE, ACCIDENTAL RE-VEG FROM TIMER MALFUNTION OR HEAT STRESS?

Most of the main tops have started stretching out. The cause of which hasn't been pinned down 100%. I did have a timer malfunction which gave these girls an unknown period of constant light, but have also been struggling to keep temps down. UPDATE: my research seems to be suggesting that this is what is known as bolting, which can be caused by rootzone temperatures being too high in mid-late flower. Comparing pictures of cannabis bolting vs re-vegged, they look similar, but not totally the same and I believe this appears to be bolting. Not sure yet how this will effect the harvest final weight and quality.
