Nice! First grows are always the hardest. What helped me the most was keeping a diary. Keep at it and really pay attention to what regular farmers and gardeners do -- you know the ones that don't grow cannabis. Growing roses will teach you a lot about powdery mildew and aphids. Growing tomatoes will give you a chance to battle with horn-worms and inconsistent watering. Corn is good at teaching nitrogen use and is really fun to watch because it grows tall so fast.
Going back to your plants though, she shouldn't really be burning this early, but as long as you back off a bit and treat her right, she'll be fine. In the future, you might want to get three different strains, and stagger your grow. Get an early flowering auto flowering strain, then a hybrid that will be ready in Sept - Oct, then end it with a Sativa that finishes in November.
