Purple/red stems?

Ive been digging into purple petioles for a while. Good advice there from @RM3 . Your plant looks good, avoid fucking it up by fixing a "def" that is possibly impossible to diagnose.

Often folks believe it's P but even so it's probably available P that is low. The soil could be P saturated so adding P is not helpful

I usually have a purple-red-magenta-ish to the halves of the stems facing the light. The underside's usually green. Maybe RM3 can help me figure that out, but the topside pattern makes me think that my LEDs are suntanning my plant, if they aren't just the sugar highways. Haha.

That would indicate you are in a medium nute rich environment

I dont think you're correct there. Looking at hundreds of plants with purple petioles Ive seen super rich and super lean medias produce purple petioles. My hypothesis is that it has to do with mineral balances more than overall saturations.

Ah, but are the nutes readily available to the plant ?

I grow in peat, zero charged nutes available, so all they have available is what I feed em and I can make the red petioles come and go pretty much at will. I've been doin this for a long time
