24/7 light is fine, don't worry. The fastest way to sex your plant? Cover one of the branches with a dark as pitch bag and leave it on for 12 hours of darkness, take off for 12. repeat until you see sex on that branch. the rest of plant will be unaffected.

Method 2, keep growing your plant until it shows preflowers (IF it shows them, many do)

method 3. take a cutting off the plant and clone it, once it is cloned then put that rooted clone into 12/12 light until it shows sex

method 4. Take a cutting off plant, flower out main plant in hopes of getting bud and clone out the cutting you took in hopes that mother was indeed female.

method 5. flower out plant until it shows sex, if it is female put the main plant back into vegetative light cycle and make some clones. flower out the clones once they have grown to your liking. Keep main plant as a mother.

Personally I prefer 1 and 5 as it gives you the most options of what to do with the main plant.

just so you know, plants clone fine when taken from flowering plants, they take longer to root, but in the end they grow just like a normal cloned one.
