... I'd say she starting to get hungry for more food, overall,... the spots are likely early Ca defc., and the pale upper growth the start of S defc.,...I see a few N defc. leaves as well,... time to up your feeds, gradually, star on Ca-Mg, and for the S, use epsoms salts (MgSO4), 1tsp/qt for 2-3 treatments over a week or so,.... in addition, you could also foliar spray the epsoms for fastest right-to-site treatment,...but you gotta do this method right to get good results! Critical to this is a water spreader/wetting agent, so it coats and sticks evenly instead of just beading up,.. getting the undersides of the leaves is also important-- better absorption there vs. topside,...if you want to have ago at this, let me know, and I'll help dial things in with you! :smoking:
