I am having the same problem still. I've taken everything i possibly can into account and the only conclusion that i've been able to come to is that it must have something to do with my tap water. Even though i've adjusted the ph accordingly.. alas my problem persists. I've noticed my roots are growing at an insanely fast rate however. I transplanted into 3 gallon pots not but 1 week ago and my girls are already showing roots through the bottom drainage holes.. Anyways sorry for clouding your thread with my unecessary problems. I wish you the best with your grow and hope you get to the root of that problem! Happy growin man. Definately fill out the troubleshooting form. :hippy:
