Outdoor.Looking for a top dress soil amendment opinions.4 plants in a 6.5' x 8' area.

I've already used 2 lbs of epsom.

It's Mg def, pH could be out of whack for uptake. It it simply wants more. Did you add Epsom to your mix? What do you mean by, you've used 2 pounds?

Full plant shot if you have one

Magnesium is easily leached from the soil. Well, at least that's what I've been told.

Double check pH just to make sure your in range. I'm guessing heading into flower or maturity those plants are getting hungrier though. Calcium and nitrogen are likely next.

If your not straight organic I would hit them with calmag, I know it's cliché , lol.

Due to the way I have my "enclosed,Locked , and secured facility" It's hard to get a good full picture.Pics are from today.The yellow in the first pic is from the sunlight, the plant isn't yellow .

I thought about this which will be high in Magnesium but probably is too high in salt.I'll have to check the feed tag next time I'm there.

These pics here aren't showing the Mg def. Is it only a couple plants, or a certain strain? We're narrowing it down now.

I would just keep up on the epsom. It works, I think you're plants are hungry my man.

I'll hit them hard with some Dyna-gro + Mag Pro then top dress with more epsom.
