Calcium deficiency?

Before I take any supplemental measures, I’m assuming this is a calcium deficiency. I grow organically/dry amendments and probiotics but the soil they’re in has no supplemented cal/mg supplements (except what was in maybe compost/EWC) except for pellotized dolomite lime that I added in. Unfortunately it takes quite some time to break down so I amended some oyster shell flour a few weeks ago however I don’t believe it has had time to break down yet. Was thinking maybe a tsp of milk in my next watering would be a quick fix? Or eggshell mixed water?

By the way, for anybody wondering why the soil wasn’t properly amended/broken down the reason was I ran out of soil when I had beans germinating. so I mixed some dolomite with used soil and threw in some guano/compost/ewc and popped these girls.

GH's organic line has a version of Calmag.

Looks more like a lack Magnesium , but either way Cal-mag or a similar alternative will solve it.
Edit: I take it back its a Calcium issue. They kinda look similar.

Heavy dose of General Hydroponics CaMg+ should solve it.

Needs more cowbell.
