I am terrible at diagnosing. @Myfriendis410 @MattyBear @dbrn32 @Missiles @imSICKkid
may be able to help. If it was mine. I would be guessing ph is off. I have to check my meter often as it will drift on me


Could be a PH issue…without knowing what your soil pH is we won’t know. You can do the run off check or a soil slurry ph check.
Aside from PH issue it looks like a Phosphorus deficiency to me.
I’m sure others tagged will assist with their assessments. The one thing also is how yellow the top fan leaves seem to be and that is throwing me off…


That is a good call: you can see the lack of heat tolerance/burning on some leaves. Light color indicates N deficiency too but less of a problem. How about filling out a Support Ticket so we know the particulars…

Check that with your pH levels …I shoot for 6.5/6.7 … I can’t find the other chart… This one’s isn’t my favorite but soak it up

Oops your coco…so you should be even lower…
