I also did a little detective work with the first plant. it was about 5" tall when the overheating occurred (the little room got up to 92º F for a few hours one day). All 3 of them obviously had their growth stunted, as I figured I lost a good 2-3 weeks, because as I said, they were vegged for 14 weeks total. The first plant - the one that was tallest during the crisis - responded horribly to another mild heat situation, were a new bulb got too close to all 3. That first plant's leaves got wrecked - dried and crispy, curled up all around, and yellow spots all over the edges and half-way in. New leaves are coming in fine up top, but I don't expect a high yield from this one, I don't think it has enough processing capability.

My unprofessional assumption is that the seedling took some genetic damage from that early 92º episode, and now that plant is highly susceptible to any heat overages.

Does that make any sense?
