not enough mag, little too much P. i's say cut back on the ppm slightly, and foliar spray with a little epsom salts

Growing in DWC, so need more magnesium?

yeah, but i'd still go with the foliar spray, instead of changing the nute ratio. at a guess, i'd say maybe their ph is a little low.
it doesn't look calcium deficient, or iron deficient, both of which usually go hand in hand with mag deficiency, if it's from under feeding. so the other easy thing to check i ph....is your meter calibrated properly? when was the last time you checked it?

Been a while since I checked my meter, that's probably the problem
