Hey B.....top of the day to ya brotha. Why are you gonna cut off the top?....to sample it?
Don't do it....leave it alone ...by the looks of them another three weeks should do it. Two,will not be enough.Those buds are so ...not ready ,or near ready. They are still building .No sign of withering ....pistils are all still healthy and multiplying. If you leave them alone....they will reward you for your patience. Cheers .
