Those spiky things are leaf "hairs", otherwise known as "non-glandular trichomes" and are nothing to worry about, they are compltely normal for cannabis. Stay off those gum leaves!

Fungus on plant
I know where it comes from... I was too stingy and didn't want to turn on the heating on cold rainy days- air too humid. Can I somehow save the affected bids or do I have to remove them? ( Just fan without heater I’ll have about 10*C)

Should I keep this deformed bud or cut it off? The humidity is high, and the sugar leaves are layered on top of each other. I'm a bit worried about potential mold. Any advice would be appreciated!

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 ?

7th week flowering mold problem. What can I do?
Hello everyone, in the last few weeks unfortunately I have eliminated some florets because a bit of mold has been created, I do not think it is real botrytis because if it was botrytis in 2-3 weeks it had to infect all the plants, it is a small percentage that I have eliminated .

Fungi around the seedling
I've noticed some small mushrooms coming out of the soil - I used mycorrhizae around the seed holes, but it's supposed to spread through the roots. There's also some greening on the parts of the soil like bark. Is that a good sign?

Good cover? Enough light passing? I place her at inside at night. High risk of budrot?
Is this a good cover? Quite bad weather this week, but i live in northern Europe so we have a mild sea climate. The summer is kinda over but this week is more rainy and cold then usually this time of the year. Does enough light pass the cover? I place her inside a barn at night.
