Need help

Howdy Shag129, with the little information that You posted, it would appear to be a pH problem. I do not use pH pens because them can give incorrect readings (even the good pens) when use incorrectly or stored improperly. That is why I have been using pH test strips, they always work, no calibration or batteries required! (LOL!).
Good luck with Your grow.

Not really with out any more info. Need info on nutes, setup, temps (tent and res), pH ect. How do the roots look? How does the res smell? Are you properly aerating the res and keeping it below 72 deg F and keeping biologics out of the res? It definitely doesnt like what you are doing, but without knowing what you are doing we cant tell you what the issue is.
