Just switched from coco peat on my first run (thought it was coco lol) now I’m on 70/30 coco perlite for my 2nd. Just wondering if you notice anything or have any suggestions. I see discoloration of the leaves could it be excess Potassium? Thanks!

Here’s what im using:
2x Mars Hydro Ts-1000
73-77 F
Humidity 55-65
General hydro flora Trio and cal mag
Feed once a day 10-15% runoff
500-700ppm
Runoff ppm usually 550-high 700s
