PM covered plant sentenced to death - What would you do?
I'm about to destroy this plant. Each branch has heavy PM despite having ample airflow. I suspect due to the lack of direct sunshine, but I'm sure it's spread to other plants which will also be destroyed. Is there anything I can do to salvage? What would you do? Thanks!

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?

Unexpected guests - mushrooms
I discovered these little puppies growing out of my soil, should I worry or is it a good sign? I'm using Canna Terra Professional Plus, water pH'd to ~6.5, don't know the soil's pH though.

Small bud rot - Harvest or finish off? 9 weeks into flower
I've had to cut about a 1 inch section off the top of one of my colas due to what appears to be rot. I've checked the rest of the plant and can't see anywhere else that has been effected. Should I harvest now to be on the safe side or let it finish up?

Mold between the pots and on the soil's surface, should I be worried ?
So my pots are very close to one another so they can't breathe enough but my space is quite limited and in veg maybe there was not enough extraction. Now that they are in the flowering room they have a little more space but still too cramped. It's just one or 2 pots out of six

Harmful mold/rot/fungus on degrading old plant matter?
Mold/fungus? Harmful? Haven't seen something like this in my living soil and I suspect it could be from high moister or humidity level. Its only seen on old dead cover crop.

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?

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.

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)
My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays. Res/Tray@ 6.0PH/653PPM. Coco slurry @6PH/500PPM

Should I throw a net on her to limit her height or continue LST and leaf tucking? I’m siding with the latter but maybe it will help her in flowering as well if I spread her canopy under a net? Week 5 and showing pre flowering.

Best way to control humidity?
I have a 4 inch inline fan blowing in air at the bottom, I have a 4 inch inline fan sucking air out the top and a 4 inch fan to circulate air inside and a large 300 foot air dehumidifier in the tent but my humidity is still 50%-60% constantly. What am I doing wrong?

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!
