What Def. Is This?

Hey everyone,

I am having massive issues!
I am not sure if this is mag or potassium deficiency, and maybe one plant has both?
I am pretty sure I was underfeeding them, so I upped their nutes to an ec 1.5ish.
Medium=DWC
Ph=5.8
Leaf Temp=77-80F
RH=55-60%

It's two plants, one is blueberry muffins and all gas og.
The BM seems to be stunted, while the AGO is dealing with the deficiency a little better.
I am using GH line but recently received Jacks 321, and will try it out next res change
