Question was....Is it one. if you have grown out a bunch of males and want to teach someone.......go for it. In other threads I've said how I've done it and keep pollen.
Been answering these threads for years and if not 100% sure even if it looks sort of the advice is always to chill and allow them to fully form. I see why say male but i dont see fully formed and also one or two parts that dont look yet ready to show. Many calyxs look spade shaped too and hundreds of threads where peeps swear its male and then a pistil pops out.
There is simply no confusion over fully formed male/female parts but many jump the gun at the first sign.
Id be keen to wait, if it is a male these will swell and bunch with more so why advise to kill when theres a slim chance it might not be.
Also some just dont understand imperfect preflowers and always say male which causes confusion and argument so there is a third factor that i and others always teach if you want to use that word.
Its all good and just debate and i dont mind being wrong if someone is willing to show a little patience.
I feel most of these male or female threads start because even a six year old could tell a male from female but at this stage its not completely clear hence why the op posted.
