Small celebration.. but prepare for the important part of the grow. Veg only takes you so far, flowering gives you what you really want. Keep at it and always ask questions on things you don't know about before you decide to test anything that is potentially dangerous to her. PMS happens to all types of females, human or plant, problem with plants is... they can't talk to tell you whats wrong, so don't piss her off haha. Enjoy the ride! Flowering is the fun part. I am assuming this is your first grow?
