Sick baby. I dont know what the heck.

Coco. 5.8. 600 ppm. Cal mag, flora nova grow, 80 f 45% . I've tried all kinds of stuff. Looks over watered and heat stressed. Lights on 50% 18" away of led. 6" exhaust on setting 4, 3x3 tent. Oh, Epson salt also.

Looks pretty crowded with all those big leaves. Could it be just too many leaves too close together for the current air flow? Seems unlikely it could be over watered with a fabric pot and all that perlite.

I don't think over watered.
Coco is nearly impossible to over water.
Definitely something not happy.



OP.
Check for bugs under leaves and in the soil.
Could be soil mites or broad/russet mites

A phosphorus deficiency can result in red or purple stems, accompanied by symptoms like darkening and curling of the leaves, reduced flowering, and slow growth.

Wrong site ?

how much Mg did u give her ?
in ppm for last 2 weeks ?

Hate to see a plant suddenly do this.

I'm not a coco guy but I've grown in it before. So I'll just see what others post.

I’m a coco grower but I use a different technique. You say you’re at 80 degrees and 45% humidity…..that’s a Vapor Pressure Deficit of 1.9. Ideally in veg your goal is between .8 and 1.1. So that means your plant is giving off water vapor faster than it is taking it in.

A few questions….How often are you watering each day? Are you getting runoff with each watering? How big are those containers and how much water do you estimate you’re feeding them each time. Do you measure the ppm in your runoff? Do you leave your rootball in the tray with the runoff water or do you have a pot lifter to keep your plant out of the runoff water?

I suspect it’s a combination of your heat/humidity and watering practices.

Edit….fixed my grammar so that I don’t sound like a hillbilly. Haha

I went back and asked Microsoft Copilot about the impact of a 1.9 Vapor Pressure Deficit…..seems to match your plant’s symptoms.
