Personally I think you should start fresh, with some new plants and lessons learned from this time around. Even if your plants make a recovery and starts creating some bud sites, the bud will be so stressed because of the veg life that it's highly likely not worth the wait, expense, and effort. I'm not sure how easy it is for you to get some clones in your area (it's easy in Cali), but you can order seeds off the internet... it works, trust me. Then you could start getting all of your supplies and tactics in order while the seeds arrive, so they'll be ready to go on a happy life... and your grow will have stepped up many notches in a short period of time (compared to waiting for your sick little ones). Then you could clone the good strains you get and have a regular supply of whatever you choose to grow.
Depends what you're trying to get out of your grow, but that's my opinion on your situation.
