falling over

I have two auto white widows which suffered nutes burns. Buds have dried up, except for a few top budds, n leaves have fallen off after clawing. Plants are 65 days old. It happened when i gave em final dose of nutes w water. Any recovery option available ?

Grown in soil, and hydro. This is hydro bucket now. Last hydro plant was falling over as well, weak stems. How much air movement should I have in my tent (4x4x6.5')? Pic shows the two fans, also have an exhaust fan in the tent. Thanks for any input!

i carried it to my bathroom to the tub flushed with a couple galons and its falling straight over without support it could touch the ground did i do something wrong
