I feel your pain bro. I found out just the other day that one of my plants was male - shit sucks!
I still have two more to go...
It wasn't really a waste of time, think about it..you got some experience under your belt if you made it this far. You will do better on your next grow.
Remember..the most exciting things is having these babies sprout up and watching them flower. You will be at that first part in no time.
