This plant had root aeration problems from the beginning. Then I transplanted into another soil better mixed and prepared.

I noticed pink spots 2 weeks ago and thought the leaves will turn this color. But, today I used a lens to zoom and here is what I discovered:

Any thoughts?

Hey Weedarast - That's a great post you started there, telling everyone everything. Good on ya. Is that Can a 14/12 a calcium magnesium additive?
If it isn't, then maybe that's what you need.

[Weedarast]

No. That's P K additive. Mg is included in powderfeeding series. I'll try some cal.

Weedarast I had a similar problem with a few GSCs. My problem was that my LED were too close. The LEDs burn the leaves a little different the say HPS. I moved my like an inch past the recommended height mroblem gone. Does it feel and look like a rash on a human?

It looks like teenage face pimple. Try to zoom on 1st photo. Has whitish head. But the strange thing is that is mainly on lower leaves. So I don't think the over-lighting is the cause.

Actually, was. Cause yesterday I removed most of leaves. Today plant looks very well. Continuing observation.
