SSH Light green

Any photos of the plant?
And ya it does look like a mag diff.
But if your adding epson salts with every feeding that should take care of it.
How much salt are you giving them per gall and is there any Dolomite lime in your soil?
if you are using soil?
Allso check your run off PH and make sure its around 6.0-6.8 in soil.
mag gets locked out of hydro/soil around 2.0-5.7 PH.
So you might have a slight low PH problem.

Just my opinion

Sir.S.S.

I don't have pics of the whole plant right now. the bottom looks to be a little draker/normal. Yes I got dolomite lime in the soil. I'll try checking the run off ph. Thanks

The dolomite lime in your soil should prevent a Mag diff allso and allso keep Your PH stable?

Hope things are getting better.

I upped the epson salts a little and now it looks to be getting better. But now some of the leafs are sarting to get some rusty looking spots on them, just a couple. I think I'm just gonna get some calmag to use.

Heres a pic of the whole plant by the way
