Dat_Maltez_Loud
started grow question 3y ago
There is some sort of mould on the top of the substrate. I think I will spray it with diluted hydrogen peroxide. Is this a good Idea?

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?!?

Moho in the pot
I have a little gray mold on the bottom of the geotextile pot. I am using bioenhancer which brings beneficial bacteria and fungi such as trichoderma, do I have to get into trouble? How do I remove mold from fabric without damaging the roots?

Bleu (largest of the 3 plants) is ~14 days behind the other 2. Is such a variance in size & rate of maturation common when growing from seed? Does LST/HST amplify the differences between phenotypes? She's so tall I'm worried about light stress. Should I reduce the light schedule?

Organic growers: question about mold
First picture includes both molds. Second picture is the 'spider-web' mold. (Good mold, correct?) Third picture is the unknown mold. (Is this good or bad mold?) The red wrigglers living in the soil eat mold, but can/should they eat the second mold? Should it be removed?

Infected Leaves. To remove part of the leaf or whole leaf?
I had had pests and disease issues my second grow of Autoflowers. I believe it was hemp russet mites which spread disease on parts of many of my leaves. Would it be alright to remove only the part of the leaf that was infected or to remove the entire leaf?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?
Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

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?

Mold/fungi or am I paranoid
I 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.
