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.

Bud Rot? Mold? Or safeOne of the branches split during a storm the other day and didn't recover after a few days so I chopped. I'm wondering if the leaves trap moisture in the bud during the days I let it recover. The backside has a brown tint to it while the front looks green and healthy. Srry 4 picsBuds. Other

Mold/fungi or am I paranoidI have never seen all these white strands when looking at the trichomes so I was just wondering if this could be any time of mold of fungus? It doesn’t seem like it when looking at it but I have never had buds this dense and close together so just wanted to be safe.Week 10

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue?
Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.Leaves. Color - Black or grey

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?Week 22

H2O2 bath for light PM on pocorn/trim, pre QWISO?PM found on trim, post harvest, my bad darnit. *Very light* but I take pride in my work. Personal consumption only. Forums reviewed so lets skip the chatter, will proceed with QWISO. Should I do a H2O2 bath before extraction in ISO? Trim off best plant, Dos Si Do which is strong.Week 19
