<span class="link_user">@BudVision</span>, Thank you BudVision! Its CRAZY I have tried everything. pH is hovering between 5.8-6.1 (great), temps ~65 lights off and ~73 lights on (great), ppm on the lower side, lights I have tried anything from 18-24 and can't seem to move it closer than 20, and all autopot equipment seems to be functioning properly. I mean what does a guy gotta do to see some happy plants here LOL. The only thing left would be to rip them out and check the roots, but I am going to let it run.
