Hi.
Not sure what this is. But I noticed this on some of my plants lately. It seems to be getting worse.

Plants are in coco/perlite. Almost done week 4 flowering. Fed with a locally manufactured 3 part mix. PH around 6.0 and EC 1.2-1.3

Does anyone have any suggestions? I'm planning to do a rinse of the medium with ph balanced water when lights go on again.

Thanks for any help.

How much calcium and magnesium are in your locally sourced fertilizer mix?
