Same environment but 1 Struggling

[SNTHC]

So both of these plants are in the same DWC container so subject to exactly the same environment: light, nutes, air etc. But the one is struggling with the leaves showing copper colored spots. Any ideas?

Normally pH related. Calcium lockout or deficiency maybe.

I've been feeding CalMag at full strength when is saw this start. But why not affecting both plants?

My brother and I are from the same stock and grew up in the same environment.
He is retired with a lot of money and works out. I am retired on government assistance and can't fart without pulling a muscle.
Sometimes, you just get a bad seed.

Bumper stickers are for people unable to be clever on their own.

Take a look at roots. Are they healthy and bright? could be an issue there causing a lock out.
Could be more sensitive to a hot mix. what nutes? How much? PH?
Try to rule out disease befor too long.
