I don't believe that they are deficient. Overall, they look healthy. I'm definitely still figuring all this out myself, but it looks like it could be watering issues. Like, the dreaded overwatering or pH fluctuations. My experience has been that watering issues can quickly give the impression that there are deficiencies. I suggest drying them out almost to the point of wilting and then resume water/feed at a reduced rate. Hope this helps and happy growing!
