Is this powdery mildew or some other fungi?

Hello ladies and gentlemans

I dont know, if I am in trouble or not. 2 days ago I noticed these (photos atached). I am nervous about this little white hairs and somewhere around the leaves there are also something like crystals or whatever... could it be nutrients coming from leaves (probably bullshit) or some funghi? It is Auto LSD from Barneys if it helps.

Thank you for any advice

What are your temps and humidity levels? And did you say it looks like hair? Possibly webs? You can check for bugs/ mites with a microscope

Yor temps and RH look to be in check. Do you have a exhaust fan running and a fan in the grow tent gently moving air over your plants?

PH is 6, exhaust fan is running when the light is on (14 hours per day), plant is moving a waving itself but only a little. Growing in room without any tent, trying to change air everyday, plant started 6th week from seedling now, growing under 11 CFL (5x 2700k, 6x 6400k, going to change it tomorow, coz its already in flowering stage)

If it gets out of control you can spray regalia by marine bio it works well and is safe. Just use it if you have to though. Control your temps and increase airflow and you should be fine. Don’t go above 77 degrees imo

You want your temps higher. If your temps drop at night your humidity goes up. You need it to be warmer at lights out around 26C. It’s the drop in temp and the increase in humidity. Time for a space heater. I had the issue. That’s how I fixed it by running a space heater in the back room to kick in at certain drops.

Also you can mix hydrogen peroxide with water and spray the leaves at lights out. That’ll kill the PM.
