Tips look burnt. What is your ppm? How about your ph?

I'm using pro-mix hp with ph at 6.5 and my ppms are at 200. And I'm using the whole fox farm line.

try lowering ph to 6.0

Is 6.0 ph good for pro-mix hp? I've heard 6.5 is more desirable??

6.0, 6.5, I'd lean towards 6.0. The soil should buffer it. Anyhow, that is important, but equally important, is your run off ppm and ph. You can see how the plant gets your nutes, and what it does to them.

i'm using pro mix also it's soilless my ph 6.2 seems good 5.8 was to low 6.5 was to hi
