Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!

Peltier dehumidifier @300ml per day adequate for 3x3x6 tent? Alternatively, a conventional dehumidifier outside the tent?
Peltier thermoelectric dehumidifiers extract 300ml of water per day. Weak compared to compresser units, small and use less energy. Is it enough? Would a conventional dehumidifier set outside of the tent near the intake be effective, or does it need to be inside the tent to work

Is this Soil Mold Safe?
After rainfall, I notice mold on top layer of soil. Approximately 70 days from seed. Photoperiod, outdoor grow in 7G fabric pots. I know powdery mildew and botrytis is a death sentence for plants in flower, but with these girls in veg - is it okay? What should I do?

Pollen sacks or powdery mildew?
I noticed what I thought was powdery mildew on a leaf, then noticed funny looking things right next to the powder. I think these are pollen sacks, and if they are I want to know if anything is recoverable, or if I need to scrap the whole plant/grow. "Second Grow" on my profile

Bleu (largest of the 3 plants) is ~14 days behind the other 2. Is such a variance in size & rate of maturation common when growing from seed? Does LST/HST amplify the differences between phenotypes? She's so tall I'm worried about light stress. Should I reduce the light schedule?

Bud rot! Should I harvest early?
I wasn’t finding any mold or mildew except a few leaves until today. Had about 4days of rain and now there’s a bit of rot in every large bud it seems like. About 10 days of sun coming up now, so should I just cut the rot out and wait 1-2 weeks? Or chop now and make hash?
