Thoughts on Cal/Mag during flower

[Dman91]

Fairly new grower here. I am curious when I should stop using cal/mag with my feedings. I am using fox farm ocean forest soil. The nutrients I am using are the advanced nutrients sensi bloom line. My plants are both looking healthy going into week 3 of flower. My only problem is that I am seeing some deficiency. Any help is greatly appreciated

Its prolly the time to stop cause that looks like a calcium toxicity....
see what others says too....
Why were you using it in first place?

Thanks for the input! I started using it because I noticed some of the stems turning purple, and some light spots appearing on the leaves. I was hoping cal mag would help alleviate these symptoms. I will try skipping the cal mag on my next few feedings and see how the plant responds.
