What's wrong?

I'm running ebb buckets with ro water. I add 2.5mL/Gal of Calmag, then top off with VegBloom nutes until I hit 600ppm and add some hydroguard. My pH is 6.1. The plants are showing signs of CalMag and Nitrogen deficiencies and I have no idea why. It seems to be getting worse today too.

You need to feed stronger. Veg+bloom is recommended 1.5EC which is about 1000ppm. Next time try to feed around 800 atleast.

I had it at 1000ppm when this happened and brought it back down to 600. You ever try their bloom booster? I was running that too
