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?

Mold ??
Hi, This is my roommates plant. I think it’s starting to get some type of mold on it. He sprayed it down with baking soda and water I guess, not sure how effective that is. What do you guys think it is? And what should he do? My plant will be going out there and I am worried.

Should I defoliate during flowering outdoors?
(Autoflower) Should I defoliate? I made the rookie mistake of doing NO defoliating or lst during vegging, cuz they were skinny then. Did minor defol during flowering.It’s in full flower with 2-3 weeks left and we have about 7 straight days of rain. Worried about wpm and bud rot.

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Bud Rot? Mold? Or safe
One of the branches split during a storm the other day and didn't recover after a few days so I chopped. I'm wondering if the leaves trap moisture in the bud during the days I let it recover. The backside has a brown tint to it while the front looks green and healthy. Srry 4 pics
