Yeah, looks like potassium deficiency, swapping to bloom nutes should sort that out

I gave a good dose of calmag last night. The first signs were the dark spots on the leaves.
Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength.

Cotyledon issue from seedlingHave seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue?
Now I am around 100 PPFD and put the light a bit up. See photo.
