Unlike ALL my other fertilizers, Age Old ferts RAISE my pH, not lower it. Which means if you are starting with plain water at 6.5, you are probably too high after the ferts are added. It does look like fert burn to me too, but I bet your pH is too high also.

I've been lowering the p.h. to 6.5 after I add the nutes to the water. If it is nute burn do i just need to flush the plants with plain water?

Don't flush, it's not that bad. But just plain water for a few waterings and then cut back on how much fertilizer u are using until the plants are big....

This is spot on. The water starts at 6.5 and that organic stuff is changing the PH ,giving you the rusty deficient look. Always read the ph after adding nutes .
