your plants will mature between 4-8 weeks of veg (if from seed) if you boost them with nutes, you should be able to flower at day 30-40. if you go 12/12 n e sooner than that, your plants will still have to reach maturity, will have stunted growth, and won't flower for several weeks later than it should, and greater possibility of hermie-ism.

it looks like you may be a little s.o.l. unless you can find a babysitter, or set up a self controlled unit to water, turn lights on/off, etc.

what are your temps at (where plants are)? are the leaves culing up or down?

try misting...
