Can't really tell what I'm supposed to be looking at.

But I've never had a p or k def using far less ec of the same nutrients..

Personally I'd back it down to 1.6ec but test your run off as a precaution first

I don’t see anything nutrient related. Dark green on most leaves indicate plenty of nitrogen. Try cutting back on just the nitrogen for a while. Cut back. Not totally out.

Then you ain't locked out.. Still it's high EC going in but that's up to you.

Those little yellow blemishes could just be the light .. just keep an eye on it for now
