Leaves Yellowing between Veins - Pics Attached

RU running a DWC setup? do you check water levels, ph, and ppm daily?
Do your plants still drink lots of h20 daily?

Nope. I'm running a top feed with rockwool. I check my ppm and ph twice a day, and I feed twice a day. It's kinda crazy. I had the ppm at 1750 this past week using dynaBLOOM and they sucked it right up. The water is gone, and the PPM dropped. I topped it off today but I didn't add any nutes because the leaves aren't looking that good. I have a couple different strains and some are showing burns while others are growing fat as hell! don't really know what to make of it...
