I'm very glad that did the trick. A simple fix to a horrible situation. I'm sure you mean that you have a fan blowing on the light. Looking forward to seeing pictures of those nugs.

As far as when to induce flowering, I noticed that you picked a time that seemed to be when most people do it. There is not a certain time for you to begin flowering. It depends entirely on your space available and other things, but mostly space. Some people skip flowering completely, some flower for several months. You can veg indefinitely, and and up with huge plants before you flower, thus also ending up with a much bigger yield than if you vegged a couple weeks. Just remember that they can double or triple in size once flowering starts, so plan accordingly.
