I feel that I kept my plant vegging for too long. It seems a lot taller than it should be and now I am not sure whether I should remove fan leaves or top the plants again to halt their upward growth. OR should I do nothing because they will stop growing upwards soon anyways?

Is this still good or is it ruined?
Hung plants to dry and waited for stems to snap, unfortunately when I checked the buds were so crispy they basically crumbles in my hands. I heard this could be mold/rot also. Did I mess up and over dry my buds, or is this something much more awful? Is this still salvageable?

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 throw a net on her to limit her height or continue LST and leaf tucking? I’m siding with the latter but maybe it will help her in flowering as well if I spread her canopy under a net? Week 5 and showing pre flowering.

Trying to germinate our seeds right into the soil, planted 72hrs ago. Covered with mason jars and now have white mold starting to grow on soil. The temp has stayed around 22 and the humidity around 65%. Should I remove the seeds and go to paper towel method instead?

I have some very bad news and need help. I was gone for a few days and when I returned to see how the plants were doing, lots of the buds have been taken over by mould. I am very disappointed with this and I think my only option is to harvest now. Please help!

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.

How do I reduce humidity
I have my grobox in the loft but it's got very high humidity 60-80. What's the best way to get it down to 40-50% for flowering? I already have a mini dehumidifier, 2x fans in the box. A dyson cool fan outside the box. Any tricks? Can't afford to spend mad money

Best way to control humidity?
I have a 4 inch inline fan blowing in air at the bottom, I have a 4 inch inline fan sucking air out the top and a 4 inch fan to circulate air inside and a large 300 foot air dehumidifier in the tent but my humidity is still 50%-60% constantly. What am I doing wrong?

Should I keep this deformed bud or cut it off? The humidity is high, and the sugar leaves are layered on top of each other. I'm a bit worried about potential mold. Any advice would be appreciated!

Harmful mold/rot/fungus on degrading old plant matter?
Mold/fungus? Harmful? Haven't seen something like this in my living soil and I suspect it could be from high moister or humidity level. Its only seen on old dead cover crop.
