Overwatering? Is My Plant Screwed?

It could bounce back, stop doing the ridiculous routine  of watering till you see runoff.
 
Let it dry out and go to 10 oz to a pint every other day or every 3rd day.

 

I'd dunk this babe to a bath, wash that shit soil out and transfer to a larger pot with 40% perlite to potting mix, water well and allow to sit overnight to resume next day

 

i wouldnt do this. she is already stressed enough and vostok shame on you, he obviously doesnt know exactly what hes doing over watering, shouldnt advise something so vague and complex to such an unexperienced grower.
 

Where these plants started indoors then moved outside? If this is the case it's most likely your plant is burning a little from the full sun.Leaves curling upwards is a sign of heat stress or nute burn.

 

Indeed the soils has compacted, the addition of sand, gravel or the better perlite, would and does prevent compaction in the root zone, as the roots have suffered considerable stress being depleted of 02, the easiest and most practicable method is to wash the shit soil out and potup to a medium that drains well, prevents compaction, and remove any risk of nute burn

 

let it dry up.. dont wash nothing out. everythiing was healthy before the overwatering? because what sense does washing the soil out when its water that is causing the problem.. at least let it dry out first before repotting because you will only stress it more and possibly send her straight into shock.

 

no fire without smoke

 

Vostoks right. I had similar problem with overwatering perlite helps it drain well and like he said prevents root compaction. Are you using any Nutes if so how much. Also what kind if soil u using, and is should recover remember only water when at least top 2 in of soil Are dry, also look at ph of soil get back to me on Nutes soil and ph. Also how often u watering
