Can Willyd get some help Growmies

[Willyd]

Looking for some help identifying the problem. I know y’all hate it but no ph readings and don’t know ppm of in going or runoff. I was thinking Manganese but who knows.

Thanks in advance

I added 1 tsp cal mag yesterday. I hope I see a difference. I’m in process of pulling off affected leaves.
