Once more into the breach, this time with solos. :)

[Olderfart]

Problem: spots on lower fans

Medium/grow method: Coco with 20% perlite, rinsed and buffered by me

Feed: and supplements used: Advanced Nutrients Connoisseur Coco, now on Grow A and B only. When this problem showed up, ~100EC of calmag was included, with total EC at ~1000

water source: combination of melted snow and creek water, ~100EC prior to mixing nutes

Strain/age: Mephisto 4 Assed Monkey, 13 days from head's up

light used: DIY LED, ~500PPFD ~19.5/4.5

Climate: 27/C lights on, ~23-24C lights off, 47-55% RH.

Additional info:
No idea what the spots are, but very unlikely to be nute droplet damage as plant has been irrigated through the soaker tube for a couple days now. The spots don't look like calcium issues to me, and they are on older growth, unlike typical calcium symptoms. As soon as I found this, I got rid of the cal mag and gave the solo plants a good flush with 1100 EC (including water EC) AN grow nutes only.

Any ideas what these kind of spots on older fans mean?
