Need help with Mimosa X orange Punch auto. Is it nutrition burn?

Flush it. That simple. And yes, it's nutrient burn.

My question is are you getting run off when feeding? Next is if it's soil are you running a wet to dry cycles on it. If its coco then there is a whole different path you need to be doing.

* I mean light stress. But since it looks like that that issue are just at the bottom leafs it could be from the watering as well don’t put water with nutrients for regular watering in the leafs. For spray solution i usaly use a very mild mix if I do so.

Looks bit like Lightshows and overwatering, I got the same strain but not as a auto. Take a look at my pictures looks like the same

Looks like you’ve been giving it nutrients both weeks at same amounts. 2 weeks old with all that nutrients in soil definitely seems too much. Doesn’t matter about one plant not having same reaction, every plant’s different. Could be too that your ph is off. It if was me, I would give plain ph water next time
