Take all off that is not green. It's dead anyway. You are very close and what you are going through is normal. I can tell you that the light is not really blocked as most think. The green leaves make energy and send to the whole plant, so down around the bottom where not much light is, still grows, yes ?

Good Luck, You are doing fine. What kind you got ?

I got Hawaii skunk that will be ready about the same time and I'm doing just what you are. Hang in there and let the party began soon.
