Looks like a nice week for this one. A few leaves starting to go yellow and fall off, which is good as it allows light to the lower nodes. Buds are filling out nicely and the smell is most definitely lemon, it smells awesome, can't wait to try it out.
Good diary. The photos you took clearly show the progression of buds ripening up. I'm a few weeks away from harvest based on the way your buds ripened :). Lemon, you say? Yum!!
