After looking what you giving them and your purple/pink stems, you are coming up short gen on feed.
Drop either 1 of your blooms and just focus on 1.
I'm nearly sure 1 of them are part of a 2 part kit anyways. (Grow Comes with it to give throughout entire grow)
Overall she looks like she has shortage of NP.. and when making up your cal,mag once you're batting around the 250-300ppm mark. It shouldn't be an Issue. But, yes, they're some cal spots the dose you are giving seems very low. Is it hitting 250ppm when you feed. As that's what you go by. Not by ml/l when applying the right amount of EC.
Good growing
