hey man me and you are grows are about at the same this is my first time to so check it out and see if yours look the same and i had the same problem with one of my plants to the little penute looking leaves was all dieing and stuff but realy i just let it go and watered everyothere day and its doing fine the little penute leave is not as brown/yellow but its not completly healthy either. but yea with mine when they hit that 15 to 20 day mark the shot out yes out not up realy the plant stayed the same height the leaves gor realy big which im hopeing is a sign of big buds.
