recovery

hi all.
i need abit of advice please.
ive done the most common thing with my plants and over watered, 1 of my plants is yellow theres only a little bit of green on the plant but if she was green she would look ace, my other plant has stunted a bit so i maybe lucky with that 1, my 3rd and final is a cutting (my other 2 were from seed) and she is green but with clawed leaves. i will post pics in a few hours. but my question is how long should i leave them without water/feed? i know its a bit of a hard question but will i see any movement/improvement in the plant which will tell to water/feed ?
my set up.
hps 400 watt
the 2 seedlings are in normal pots the cutting is in a airpot.
if you require any more info please let us know, and i know you will want pics il be as quick as i can with them.

thanks for any response

just let them be for a few days. If you can increase temps slightly and increase the circulation/ventilation, this will help to dry out the soil and encourage the plant to shed more water thru transpiration. She will bounce back soon enough, and when she does, readjust the environmental setting/conditions. You got learn to read your plants, she will tell you when shes hungry or thirsty. Also consider the root zone when suddenly the plants gets funny, se may be root bound and transplanting would be the solution.

Hi thanks for quick reply.
I know your right there well ventalated the temps have gone up from 78'c to 85'c. Im not sure if you can see in the pics but the seedlings are double potted so re potting in my opinion is a no no unless there is some way of doing it, also i can see rootscoming out the bottom of 1 plant, my plants are in veg aswell

Plants now in flower and doing ok afew leaves still curled, found a good way to drain the excess water get a dry towel put it in your drip tray then place your pot on top for about 20 mins (dont over do it as you roots stiil need to breath) remove the soaked towel and try to raise the pot a inch above the drip tray (i used abit of wood)
