What is this?

Hi guys
I got a problem with my AK47 plants
Air in the room feels kind of moist.

Any quick replies on what is that? Looks like botrytis ?
Thanks

Feels kind of moist? Can't you buy a cheap hygrometer? This a basic necessary equipment. Also thermometers? Good luck. -granger

Hi Granger
RH goes maximum 36%
BUT the room feels much more moist than that..

I've never seen this before too...
Seriously, anyone?

Anyone ever dealt with this?

After looking in the guide to pest and problems, it looks as if I have fusarium wilt on some of my flowering plants (just about to finish).

Out of the blue, entire branches are drying up. On some, there's what looks like dark black or grey mold on the stems, but most affected stems just turn brown and dry up. The buds don't mold, they just dry up and appear smokable.

It's like something plugged the inside of the stem, below the affected area is normal, then half way up a stem, it looks like nothing was allowed to pass, with the stem and bud drying up.

My plans are after this run, to clean and sanitize the room like never before with bleach, change the filters, and if there's anything else I can do I'd love to know.

I'd appreciate any help.

Seems you have a fungal infection. I haven't read about black spots in any literature about Fusarium. That funky leaf looks familiar though. How old is the plant?

Does not look like botrytis.

Hi Crusader, plants are about 2 months old now. The problem is located on both plants. I will do some search based on your input. Thanks for your help!

Ron what does it look like to you?

Cheers

can't tell anything in 3 of the 4 pics. can you get a pic of the other side of the leaf, and the whole plant and a close up of the stalk near the leaf stem underside? close but not an extreme close up like that other pic.

Looking at the smallest spots, it seems that each spot is at the base of a hair. And the black doesn't extend up onto the hair like I'd expect if it was insect droppings.

You say that the plants are about two months old now. So are they in flower? How long?
