HELP! Help, leaves are turning yellow!

[Novice43]

hi, new to the group as well as growing in general. As you can see, my outdoor gorilla glue plant is yellowing. I’ve tried increasing nitrogen by using natural fertilizers (used coffee grounds) but that didn’t do anything. Is this a nutrient deficiency, or just normal, pre-flowering die back? Any info you can provide would be appreciated. I’d hate to loose her!

Looks like you might have wrecked the pH in your media....coffee is acidic....just because it's "natural" doesn't mean it ain't toxic to your plants.

Ok good to know. Is there a way to fix that? Ie. rebalance the pH?

When you feed a plant you obviously consider it size. That fairly big and organic you giving isn't OK. Enough food for it size

So you think it’s a lack of nutrients as opposed to a pH problem, as per the other response? Just trying to figure this out. Thanks!
