Kinda like Ca spots.did you spray something?

Your last pic I see white on the leaves? Is that just reflected light?

 

[Stankrop]

Some of the white was diatomaceous earth

 

[myke]

Do the black dots rub off?

Phosporous and K def with the start of Powder Mildew. Which only leads me to ask another bunch of questions. What is the OP running? Substrate, lights, nutrients etc.....More questions than answers LOL, what do you think?

What does the OP mean? And also confused about the substrate. Running two aglex 600watt cob LEDs, grown in soil, using bloom soil formula 1-4-5

The plant was outside for a bit and brought it in it had thrips. The sticky traps haven’t shown anything in a week or so

Ahh and that could explain your odd deficits too. You need Monterey Spinosad. I put 1 oz/gallon of water and do a root drench. I do that every 3 days for a week or two and then once a week afterwards.
