Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼

The problem in plants when I supplying CO2
Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

Grey spots on leaves and yellowing
The leaves are looking light green to yelloe and there are these dark edges on the leaves are showing up.. Has anyone experienced this before? It was happening a bit before transplant but now it seems to be getting worse. I just transplanted within 24hrs... Stress? Overwatering?

What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

Gray leaves on buds with a massive concentration of trichomes. What is it?
No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?
