Leaves discolored

Got 2 or 3 leaves on the bottom lookin like this
About to transplant into 30 gallon pots and put em outside but still have 4-7 days before that happens. —— LED light not too powerful and not too close They are in 2.5 gallon pots now almost 2 months old in happy frog and seed starter mix. I’ve lightly dosed them twice so far with dr earths homegrown . I think bigger pots and fresh soil will help but dont want to let something carry over

That’s the start of magnesium deficiency. 5ml/gal of cal mag every time you water/feed

That was my suspicion. Thanks man appreciate it.

epsom salt is your answer for MG deficiency my guy

we dont need calmag in soil, although the hydro shop loves selling it..

A tablespoon of epsom salts without any scents in a gallon of water. A drop or two of dish soap. Spray tops and undersides of leaves shortly after lights turn on.
