That's a hard one to tell. It could either be mold or salt build up.

Is the bud rot? What to do?
Is this bud rot? I found it on two bud sites so far on my big plant. What would you do? 1) Assuming it's rot or some other infection would you just harvest now? It's like 2-2.5 weeks early. 2) Wait one more week and see and risk spread?

Humidity Spike - Bud Rot
Today I went in my tent and the dehumidifier was full and shut off and my exhaust fan broke. Humidity was at 90% for likely 12hrs. Buds were sagging. Back to 40% now and exhaust running. Should I be worried about bud rot?

Mold between the pots and on the soil's surface, should I be worried ?
So my pots are very close to one another so they can't breathe enough but my space is quite limited and in veg maybe there was not enough extraction. Now that they are in the flowering room they have a little more space but still too cramped. It's just one or 2 pots out of six

Stem issues?
Do I have to worry at all about this stem? It’s had the white bumps on it the whole time but now that I’m getting toward the end I’m worried that it could be something worse than I thought it was. Any concerns that it could be mold?

Help! It's raining for another week, and our humidity is around 65% to 75%. Should we use more fans, or what would you recommend? Dehumidifiers? Thank you in advance.

How much taller is she going to get? Every time I try to LST I end up supercropping or topping and I don't want to do that but I am running up against a space maximum.
