How do I know if I have a real gg#4 cut?

You’re in soil and running a Ph that low? Try getting you Ph up to 6-6.5 and see if that doesn’t help. Just curious, how are you determining your Ph?

I grow in coco also and I like to p.h. 5.8-6.3. I read calcium and magnesium are more available at 6.2-6.3.

I was just going to say that in coco, ph should be 6.2 or so, with EC up around 1000.

I’d hazard a guess it’s lock out.

That’s what I’m guessing. Probably from all the mag. I’d do as you said and run ph’d water through her at around 1000 on the e.c. chart, and see if that gets her up taking more nutes.

But yea… Without testing there is no way to truly know…

I can tell you this for certain… It’s cannabis!
