My leafs get a black dotted yellowish on the middle portions of them

brand new rdwc setup

Do I need ro water or can I use distilled that I have been? My brother treats water for a living and the distilled water ubuy at target is like 20 ppm

ph has been 5.8-6.3 range. It always moves a tiny bit as they

should I be 5.5?

i run general hydroponics nutes line 650ppm

Yeah likely mag deficiency. When using RO you should add cal mag. Are you using any?

Yes. But I clearly need more

How many ml per gallon do u typically go ??

I’m using a 1 gallon distilled water from my grocery store. I tested it against my buddies ro n it was 20/30 ppm high

So I go a little light on gen hydro nute lineup

Depends on the brand. Add cal mag until you reach 125-150ppm then add nutrients.
