What is this white fluff on my grow bag?

JiggleBudzstarted grow question 3 years ago

I've noticed some white fluff on the side of my grow bag. I'm guessing it's some fungus, should I be concerned at this stage? Day 23 in material bags. Thanks in advance 👌

Most likely excess salt from the nutrients. Happens a lot. Sometimes can be mould but most the time its just salts

Humidity Spike - Bud Rot Today I went in my tent and the dehumidifier was full and shut off and my exhaust fan broke. Humidity was at 90% for likely 12hrs. Buds were sagging. Back to 40% now and exhaust running. Should I be worried about bud rot?

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.

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? :(

Slimey/Webby parts of the flower? Looks like rot or mold?I removed the infected parts of the plant and defoliated the fan leaves around the sites to help with aeration. Did she go past her prime and now she is dying? Or just because of high humidity in the air?
