Add a splash of cal mag?

Added a dose of cal mag for the first time yesterday but I wasn’t confident that’s the issue.

Throwin a picture of the rest of the gang in there for science (WW’s staggered and my first ever photo seedlings)

I was using 1 teaspoon calmag per feeding per gal. when I was in soil. They don’t look too out of wack yet I think you can still correct it for sure. :+1::+1: Good luck. Ph run off good?
