Please help - 1st time, sick plant

Oh I've done that a few times. I call it aeration but idk if that's correct.

So after a feeding and 2 days shes looking better. Some of the brown is looking more green and she doesn't feel so paper like
You might have the start of a slight potassium issue, you say it's doing better now that you've shitcanned the meter and started watering properly so just keep an eye on it and let us know if anything changes
Appreciate the support!

The rains are strong. I ended up cleaning out a large tool closet in my garage and hooked up a shitload of LED shop lamps.

Just gonna bite the bullet, get a few real grow lights, and do this thing lol

She's sleeping now but I'll post a pic tomorrow.
