Mould and salt! Both! Al the hype about fabric pots,I don’t get it ?humidity is the result,I do not use them any more because of mould and the rootprunning story!! You pay a lot to dehumidify. Plastic pots and your problem is gone..
Happy Growing!

Looks like dried solutes to me... discoloration is potentially a microbe of some sort, but can't be certain from picture.

Combo of salt and algae. Totally normal. I try to scrub it off the best I can between grows.

I felt that I might get mold problems cause of high humidity, and saw an little yellow/brown under the top bud. Has just opened a bud and could see mold in one place on a bud under top bud. Should I chop plant now? Or should I just remove that one bud? :(Week 13

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 profileLeaves. White powder

Stem NecrosisSo about 2 weeks ago (should have posted about it sooner I know) I noticed some stem rot on my plant. I didn’t know it could be the first sign of something much worse. Can anybody help me identify what the problem might be? Or any steps I can take to save my plant?Other. Mold

What's your opinion on pruning off the 5th node and the top 4 out of 12 inches of growth? I have 2 plants growing too fast and I believe this would remedy it. I dont want to hurt them, but I dont need a super uneven canopy. Pruning just the top hasn't slowed it down enoughWeek 4
