Hey, hmmmm...1st please do not take mine or anyone else's opinion or advice and just run with it. Especially when it could mean killing one of your babies. While IMHO this plant is very likely a gentleman. There will likely be differing opinions out there. Bottom line only you can see anything first hand, and a cannabis plant is a terrible thing to waste. There are a TON of pics and charts available on the www to assist you.
Second, I try to the best of my ability to never give 'advice' on a grow. I will state my opinion and perhaps post a chart and helpful link or two.. I feel that all of the necessary info is available to firmly nail down on anything related to cultivation...
Anyone can come in RIU and give what they say are absolute facts on a variety of subjects...but unless you are 100% sure on your own you should always do your own research. Personally, I would not sit around with a pair of clippers ready to hack a plant based on another's opinion. Just sayin'
Now 'on the other hand'...not to play devil's advocate, this plant is from bagseed and the others were paid for feminized...IF this were MY grow I would likely chop it instead of risking the others. But again this is YOUR plant.
