Not one bit as far as I can tell. All boxes checked for a happy plant. The only thing that could b upsetting them is me shifting through them plucking and pulling pollen sacks and nanners. I come out of my grow with bud hairs and frost stuck all over me. Smells great. The ones I am finding now r now r popping out in the lower middle parts of the plants. I can say for sure they r causing me stress. After working in the heat all day and then sifting through the plants under my hps by time I go to bed I am cooked lol. Another hot day on tap play safe.Were they stressed at all?
