When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

Can I change my autoflowers light cycle withou reducing their yield significantly?I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity).
Even if I stress them, it would be better to not have mold than reducing the yield, right?Other. Mold
