Hey.
I've read everything you guys have to offer on newbie central but I just can figure it out I've taken to much info on. I though it was cal mag but nothing has changed.
Ph in feed is fine I'm doing half newts.
Medium is coco perlite.
Any help greatly appreciated.
In all honesty dude i think you have lockout vs deficiency. You fan leaves look very "hot" by the extremely faded, dry, crispy, bubbly look.
I think checking runoff ph is so important. I used to have a nightmare chasing my tail with coco until i did several grows ago.
Worry about your ec last. If what you are putting in ec's, is coming out less in the runoff, then your plants are feeding.
Only after ive ruled out ph and lockout through the runoff.
In my experience lockouts show up almost overnight. Deficiencies really show slowly. Usually first thing is a very slow fade of chlorophyll. If this is the case, you probably need to feed.
I do think you are locked up. Probably with many things, not only 1 or 2.
If it was me id give a good drink of ph'd water. No nutes until you start seeing improvement.
I hope somebody helps resolve you issue, or you figure things out on your own.
Peace
