Good morning, Lisa.
Glad to hear of some progress and sorry to hear of other struggles.
Make sure you have enough aeration in your mix as well, like perlite, pumice, etc. The worm castings are great but can be a bit dense and not allow a lot of air into the mix. To give you an idea, the Coot's mix has a full 1/3 aeration in it (equal parts of CSPM, Compost and Aeration). So, just be careful with your watering as it is easy to over do it without enough aeration.
One advantage of an organinc grow is not needing to worry too much about pH unless your water is at either extreme. The worms will bring ample amounts of microbes, but if you're using bottled nutrients those may overwhelm the microbes and may lead to a need to pH adjust.
It does look like you are having some nutrient issues, and those can be caused by deficiencies of certain nutes, like what looks like calcium in your case, or at the other extreme too much of another nutrient that then locks out others making it look like a deficiency of something but is actually an excess of something else.
What are your bottled nutes again?
