Leaf issues and remedy

I have one plant that has quite a few of these leaves at top of plant. I stated using General Organics Calmag and it smells like vinegar. Not sure if this is the problem
Growth has also slowed down. Please help

Take a picture of the entire plant in regular lighting if you can. Do you know what your runoff numbers looked like? Are you in soil? What kind?

Looks like you have a ph issue judging by the purpling in the stems. I would get a runoff sample and test the ppms and ph.

I’d watch the light height as well. Looks a little close

While you’re at it could you put up what your feeding regimen is? Is cal mag in use? Or are you watering only?

I try and keep it around 900ppm. Give nutes as needed otherwise ph water.i have used Calmag, but like i said before it smells like vinegar so i’m leary onthat

What nutes? What is your exact feeding schedule? What is your runoff TDS and PH?
