stressed plant, help?

The 2 main things I am noticing is a clawing under curl to the leaves, and a burning at the edges.

Plant is a GG4 fem, grown about 6 weeks veg then on like week 5 or 6 of flower now. Grown in a cloth pot sitting in a tub, 2 LED lights. Biggest issue is we went away for a week and I advised my roommate to water it, ended up grossly overwatered--I returned after a week to the plant standing in tub-water about 2/3 or 3/4 the height of the fabric pot, so it had some really wet roots. Drained and its been sitting like a week and a half.

In mostly happy frog, amended w a handful of gypsum, some kelp and crab meal, etc.

Thoughts? I'm new enough that this clearly looks stressed but I don't want to treat without some confirmation here so I don't do something wrong and over-nute it, etc. by mis-diagnosing my issue

thank you all in advance

I’m new myself but to me it looks like nute burn

Or heat stress

I should stress although I don't recall exactly how MUCH LED they are getting, the lights are bright enough I've done well w a couple autos, and the GG wants to stretch so at the end of that week away the tops of the buds, etc. were like 6" or less from the lights, the fans might have been almost as close. As for nute burn, less N2 then?

Not good news really. The flowering cycle is short, hence any hiccups along the way are detrimental. Just run with it and get what you can. The burnt tips and leaf curl look to be over fertilised, mimicking calcium deficiency where it’s starting at the top opposed to magnesium where it starts on the older leafs. Sitting in water is obviously very bad as you said, let it dry out before doing anything. Sit them up on something so the water runs away and the pot isn't sitting in any runoff. The roots will have been adversely affected so water next time with enzymes. They will break down the dead roots and encourage new growth.
