Any idea what this is?

Yellow patches on the leaves and leave tips, with some of the leaves crinkling up.

Happened, overnight. Checked on them before lights out and they were fine. It's only occurred on 1 out of 4 plants. No nutes or water in 4 days. Any ideas?

It seems to be some variation of cannabis. You seem to have a weed problem in your dirt garden.

I may have spilled some PH'd down water on it, 4 days ago. Curious as to why it would take that long to show.. Lights haven't really changed over the past week and as far as acid toxicity goes should I just flush it out with straight water? I've been using tap water which is quite basic, best guess using my chart is 7.5+. I can really only eyeball it down to yellow. Also use separate gallon jugs so maybe the batch of water for this one was to acidic then

Could have been something on your fingers, when you touched them.

you dammaged some leaves, not a lot you can do about that, if a lot of the PH'd down got in the soil you should flush the plant as it could damage the roots and kill the plant

It's irrelevant at this point. The leaves are damaged somehow. Theyre probably not going to recover. Just make sure it doesn't spread.

If it wasn't overnight I'd say it was a phosphorus problem.

it can take a week or more for plants to show problems so the later you resolve it, the worse the problems can get (in soil)

Yes but not health to severe, overnight. It's chemical burn or grower error by overlooking phosphorus deficiency damage (no offense savex86)
