Reviving the dead?

OK i had these plants in an AeroGarden that someone gave me. Couldnt get the pH right fast enough or the right nutes - SO - I have swapped them to soil. Thing is - they are REALLY shitty looking - pretty much all the leaves dead but they have some green left in the stem. I topped a coulple of them, but before I do anything else to the others I wanted some advice.

One plant is like all but dead, maybe a little green about an inch up. Any hope for that one? Should I chop it there or is it just dead?

Any particular nutes to try and revive these?

What about my light cycle now? Will it help to leave it on constantly for a few days?

Any help is appreciated......

first off, DONT TOP. dude topping will hurt your plants for like a week, bad time to do it. Plus, without pictures its hard to tell if they can make it or not, try to post some pics quick and there might be a chance...

Have pics on the way - they still sending from cell - One is just like 10 incles tall, stem about the size of your little finger. that oine is pretty green all the way up, no leaves at all, and I did top about 1/4 inch already.
What about nutes and lights foir now?
