Have never seen this before.

Hi guys, I'm starting to grow a new girls before my first plants finish their flowering stage.
They just have 11 days old, but one of them, to be specific, in this morning showed some kind of problem, like little brownish and white spots in some places, I'm not really sure of what it is, because I've never seen this before (and with my first growing I've learned a lot and have lots of problems, plagues, deficiency, nut burns, etc).
So any help will be nice, in order to keep learning how to grow this girls correctly. Thanks !

All Mix (Bio Bizz)
I water when the soil is dry with PH balanced water at 6.0. (Just watered twice after transplant into bigger pot, using Root Juice Bio Bizz the two times)

Try using 6.5-6.8 ph'd water. 6.0 is a little low for soil although cannabis does prefer a slightly acidic soil.

Ok, I'll start using 6,5, but no Idea about the spots on the leaves?

I'm not sure. I have a few seedlings with the same issue as yours, some of the first true leaves have actually paled up and died. I have transplanted about a third of them and they are bouncing back so I'm going to transplant the rest of them today. I'm guessing it's a ph issue since I have not fed them any nutes yet. That's why I suggested you up the ph and see if that helps. You check the bottom of the leaves for bugs?
