My single auto is being grown in a grow box and I've trained it to stay low.
It's been doing great until three days ago when I saw yellowing leaves. Today it's worse of course. After this photo I gave it water and fed it with GH micro and flower only. I feel like it's lacking in nitrogen. It seems like it still has a good 3+ weeks before it's ready so the timing isn't great.
Any advice is appreciated.

That looks like normal mobilized nutrient reallocation driven by the plant's current age. Resist the urge to pluck them until they've been sucked dry. No matter how well fed your plant is, this can still happen. Nothing is wrong. You're doing fine. Don't try to fix it.

The yellowing leaves won't just pluck off. I tugged a little bit and they didn't pop off so I left them.
Thanks

Damp feet and roots will suffer. Clean dry enviornment works best. No need to tug at the leaf they'll fall off and rot.

Dont feed nitrogen its way too late for that, its a normal fade.
