Yellowing during mid-flower

Hey folks ,
This is my second flowering cycle & I’m not sure where I’m going wrong my feed has been consistent giving them no more than the minimum amount suggested on the nutrients. Following a two-part feed with carboload and sensizyme. My lights are about a good foot if not more away from them.

Seeing at least potassium deficiency.

Are you adjusting ph?
You're using the min recommended dosage? Or the recommended dose?
Overloading nutes can cause lockouts and when your mediums locked out the plant can't uptake what it needs so even tho you're putting a ton in it's just sitting in the medium unable to be used up by the plant. It has to do with osmosis and that other thing... You know? Fuck where's grade 13 bio when I need it. Oh ya I was just sitting in the back throwing paper airplanes high as fuck anyways....

Diffusion!
See I knew it was in there just had to start the ol diesel engine up. Takes a sec to warm up
