I agree with Mr Weeds Auto, she is showing signs of a mg deficiency, also a possible lock out stopping the plant taking up the nutrients it requires, if your 100% that are not "hungry" (you have put plenty of feed in) then it's probably nutrient lock out, flush and start again on 1/2 strength dose, again without all the info or diary to go off its difficult to give a proper assessment, happy growing 👍
