Is this a deficiency?

Hi all. Wondering if this is a magnesium deficiency. I have treated it twice now with Epson salts. It's in a 30 gallon fabric pot of soil. In the 2nd week of flowering or so.

Hiya @Joshthornbury When you say treated what do you mean? Foliar? Looks alot like cal/mag issue's I've had indoors but I've never separated the cal out of it, just went from no cal or mag to a cal/mag supplement.
