did you spill some Nutes by accident, they look like burn marks, are they damaged underneath as well ?

Agree but looks like maybe sprayed on🤔

Looks like nute burn, maybe, or an early calcium/potassium deficiency. A couple of those tips are burnt. I don’t know much about RWDC though, what a good ppm should be (the plant looks a month or less old?), or how cal-mag should be applied in such a system. Got a pic of the overall plant? Good luck.

I agree, but I suspect it dribbled ,
drops on under a strong light will burn spots. it’s like a magnifying glass.
I can see the spots shine through but that’s about it. Its only on the older leaves. Don’t think i ever spilled nutes on them. I have 4 plants going. 1 is doing really good. No spots. 2 are doing good but have some spots. 1 kinda stopped growing, still growing roots though
check ur ppm. plan to reduce ur ppm. it looks like nute burn from inside out
I was wondering if i was a little high on ppm. I lower it a bit.

Most burns are two sources: nute overdose and PH out of balance.
The exhale CO2 bag will be a very good thing…once the first 3 months it takes to get going is over.

I’ll bet you may have made a feeding just a tad to strong, because they don’t look very bad at all right. just cut back on the nutrients for a couple of feedings say to 50% and see what happends.
