i wouldnt worry about the pistils yet you still got some weeks to go yet on a haze, the times given out by the seedbanks though do tend to vary quite a lot did you count the start as when you switched to 12/12 or when they showed sex?i have a problem with 3 gian haze plants, they have been flowering for over 9 weeks, the botttom of the plants seem to be ready but the pistols at the top are still all white,, the plants are also very tall and the branches are very long
