Fastest way is Floral Spray with Cal/mag 1 hour before the lights turn on… Most Cal/mag have directions for it on the bottle for rates…

Or you can spray Epson salts

Just a FYI

The damaged yellow leafs will not come back…

But you also need to come up with the problem why this is happening… Is it Ph??

What is your run off Ec and Ph?
