Any idea what may cause this?

Purple Lemonade auto in flower has yellow spots on leaves. It’s growing in FF ocean forest soil, fabric pot, with FF Trio nutes.It doesn’t seem like it’s getting worse or better, so I’m not sure what I should do (if anything). Anyone have any idea what it may be?

Looks like calcium deficiency, maybe mixing with magnesium in that second pic.

Or thirps but in a tent less likely always good to check under side of leaves

Calcium deficiency pics, also in ocean forest

Thanks! Nothing on the underside I kind of ruled out thrips. I’ll look to add more cal and mag

What water do you use? I use fox farms, when I use tap I dont get calmag deficiency. When I use ro I do

GroBuddy I had that issue with Ca and FoxFarm using straight rain water. I went back to well water until they go into flower.

Yea rain water has minimum to no ppm as well

I use tap with FF actually. But when I started the grow i used distilled only.

Distilled is the same as ro in the sense its bare of nutrients.
