Humidity won't go down because of clay pebbles ?Though my extractor is at high speed, I have a hard time with controlling humidity, I hardly go under 68%, specially during the night. Probably it's the clay pebbles since the pots don't have a lid. I placed the temp/humidity probe near the tallest leaves. what do you think ?

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!

White spots on lower branches So this last week a few lower branches developed white spots that seem to cause deformation. Is this some kind of mold and do I need to do something about it? I’m worried it will stress if I let it be. Thanks in advance!

Mouldy, webbed buds The humidity was too high when I went away and now my buds are mouldy. Obviously I’m heart broken (mainly at my own stupidity because I should know better!) and I wondered if there was anything I can do to recover some of the crop. Can I wash? spray? Dry out…basically anything?!?
