Whatis wrong with her?

Don't look like Phosphorous to me. I determine that by the colour of the stalks. They are green with only a stripe of red. I think it's a micro nutrient issue, namely Molybdenum. Could be due to cold temps in the space too.

It's a phosphorus thing have u been giving it a lot of bloom stim let dry out a little and flush with 2m per lt of oxy pluss hidrogenproxide flush roots with straight water and hidrogenproxide

Possibly a ph or nutritional deficiencies.. are you consistently checking that? But looking at the photos is at the beginning..
