Normal trichomes or something bad?
Dumb question, I started noticing this on my leaves. I recently battled with insane humidity which I was just recently able to fix, and was wondering if this is normal/my usual over worrying or if it's some sort of mold/mildew/fungus or something I should actually worry about.

Brown spots - can you tell what that is?
Brow spots appeared on middle to top leaves (lower leaves are perfectly fine). I'm using a common soil "ready to use" from a gardening supply store + Earthworm Humus + some inert substrate, and didn't add any veg fert Can you tell me what it might be happening and how to fix it?

Что за ржавчина на моих листьях на 126 дне? Это дефицит cal-mag или проблема с корнями? Как вы думаете, как выглядит моя девочка? Созрела ли она?

Brown Spots, Any Ideas?
Anyone know what is causing the brown spots on the leaves? So far it’s limited to one plant, and it was closest to grow light. PH of soil appears to be normal, and I have not fed any nutrients yet. The water in my house is treated with Calcite/Corosex for PH correction.

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?

[Athens Growers - tap water and salts]
Hello fellow growers! First timer here. Noticed salt residues on top of leafs (D19 pics). They come from the mist maker who controls humidity levels 1) How to treat their leafs? 2) a tap water filter will improve the situation or salts are normal? Peace! 👊
