... is if your plant has suffered some stress, and the fan leaf has more than 50% damage on it... then yeah, cut 'em. When doing so, ONLY use scissors or a razor blade that have been sterilized by flame or alcohol or lysol. Fire good. Use the top of the flame, and don't be afraid of a little blackening on the sciss.

If you don't /have/ to, DON'T. The fan leaves are a part of the overall mechanix of the plant, and unless you have to get rid of 'em (for disease / pests / damage / drought), leave 'em be. If you must remove some parts of 'em, try to remove only the damaged/dead bits. And make sure your scissors are sharp.

I had a friend a while ago who lollipop'd his plants, but that was only in the last 2 weeks of flowering, iirc. Killa widow, mon...

If you have to help a plant out that has suffered some stress (or had to have some bad foliage removed), SuperThr!ve is your friend. Get some. It really helps, particularly with some Dutch M4ster Penetrator as a foliar spray...
