If inside get a good dehumidifier. Then you don't have to use anything on them that you will end up smoking later

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?

Mold or spiders?
Is this mold? Is the whole harvest ruined or just the buds that show mold? This is the main cola on an untrained plant.

Mashrooms and Plants Height
Is the height of the plants too much? They seems too high and weak. As you can see in the pictures I have to remove mashrooms every day, I reduced humidity value down to 55% and I keep open the room window and closet door to ensure air recirculation. Is it so bad?

mold instead of seedlings
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?

Bud rot or normal?
Hi guys does this looks normal for this stage mid-late flower? Lower leaves are starting to die off which looks normal but should leaves between buds be doing the same? I hope its not the start of budrot? Have fans on buds RH is 60-70% in greenhouse+dehumidifer+heater struggling.

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?

Beginning of Budrot
Is this the beginning of budrot or just the plant using the leafs (sugarleaf actually) as nutrients? I'm in the final week and in 2 days this leaf starts turning yellow on the bud. Bit worried. I cant pull the leaf out and bud looks fine but still worried

Autoflowers with high humidity during night and rot, any solutions for high rh?
Hello everyone, today I woke with a plant rot on some parts, that due to the high humidity it got during the night, 88% and 18 celsius. What are the cheap and effective ways you do to prevent rot? I was thinking of switching from 18/6 to 24/0 but I don´t want to stress them. Thx

Height issue. Small tent. LED as high as it will get and the tops of my newly flowering efforts are a mere 3 inches from the grow light. A few fronds have burned a little. My ScrOG is nearly as high as it’s going to go. Is there a way to decrease height. Stakes in soil ?

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?
