My new growth is very slightly starting to show some nute burn on the tips, should I be backing off on my ppm a little. Plants are 6.5 weeks old and the ingoing ppm is 680-700 with around 500 at run off, ph is 5.8.
I’m in the similar situation just now. Your ph needs to come up to 6.5 - 6.8 so there’s a definite issue in the making there. What’s your PH going in. I would back everything off and monitor. That’s what I’m doing, every time I water just now I will be watching my PH and expecting a bounce in my PPM as well

Some pics in natural light would help out.

I will post some in the morning, lights are out now, thanks
@Jimmygti no worries, there are a few that grow in coco here but I can’t remember who they are. I don’t think your PH is too far off but not sure. @Myfriendis410 should be able to shed some more light on the subject.

That’s just fine. I run everything at 6.0
