Problems (leaves vein yellowing) on Transition week

Info:
Coco grow, PH 6.0-6.1 (water + nuts only, not using ph ajustment products), using all GH products at around 80% recomended dosage (only calMag using more because its coco)
12/12 since 3 days ago
around 50% humidity at day, 65 at night or so
DTW with around 10% run off

what are those marks on leaves, mostly on veins, starting on edges before going to middle, they are spreading, is it PH related? Nutrient? Thanks

I would lay off the nutes for a couple feedings and see where your at after.

You're in coco; don't stop feeding the plants, period.

How much CalMag are you feeding and how often? Can you provide full plant pics? I would think your pH is ok, provided it is what it is and not much higher. I have found though, that as you push further into the 6 pH range, coco grown plants will begin to show deficiencies.

5ml/gal calMag, around 2x recomended dose, water 3x/day
plant seems good overall, this symptoms started on the switch to flower week
maybe it can be some micro deficiency? since she doent show any nutrient burn will try increase Micro to 100% recomended dosage

Overall your plant looks pretty good, but yeah, you can see a slight issue noted on your leaves. I wouldn't change much; your plan to up your micro seems like a decent move. Just be sure of where your pH is. Good luck.
