Throwdown in T-town

I’m dealing with my first true “nutrient deficiency” on one strain (66 cookies), I believe is a potassium deficiency she seems to like a higher ph.. I started working down to 6.0 and she definitely didn’t like it.. so I’ll adjust back to 6.3-6.4 where “p” is available and wait for her bounce back before flipping to 12/12!
