Thanks man! I devote a lot of my time to my plants, so that means a lot..
I generally fall under the "leaves are solar panels" club.. The only fan leaves I take off are ones that come off with a gentle tug. If the leaf is holding on pretty tight then I leave it. Even if the leaf half dead, the plant can use the remaining nutrients in it, or it can take a little damage that would have spread to another leaf otherwise.
That being said, I have seen some people trim a SHITLOAD of fan leaves, and somehow it works out, and it seems to help yield with the extra light. I think a good middle ground is leaving the fan leaves, but instead spreading out the colas via SCROG or LST. That way you still get the better light distribution but without having to take off fan leaves.
So I wouldn't worry about it too much as MJ is pretty resilient. Unless you took a ton of them off, it should be fine. A few won't hurt.
