EXCELLENT, thanks mate!
Sadly yes, they definitely are 100% identifiable male flowers.
If they are appearing everywhere you have little option, unless you want, for whatever reason, seedy flowers or if there are only a few here and there, you could try picking them off as they appear. Missing just one though, can result in the male flower shedding enough pollen to fertilize hundreds of seeds. You have about 1-4 days from when the male flower is "born" until it is mature enough before it opens, so you will need to check your plants very often, as much as every 2-3 hours, just in case you missed any previously. Your/my worst nightmare is missing one then finding an open male flower in the morning that has been shedding pollen all night. These days, I just get rid of any plants like this, heart breaking as this seems. Remember too, seeds made with pollen from hermaphroditic plans will grow into hermaphroditic plants themselves, so these sort of plants are useless as breeding stock too.
Pollination, from when the pollen grain lands on the pistil and fertilizes the ovule at the base of the pistils and within the calyx, takes approximately 20 minutes, so finding each and EVERY male flower is vital to prevent seedy flowers. Misting your plants or any other home "remedies" are largely useless, due to the sheer amount of pollen released by even just one missed male flower and the very short time frame of successful pollination of the ovule/seed.
I too have had supposedly "feminised" seeds turn male/hermaphrodite, usually autos and very, very, very rarely with photo period plants (I think one photo period plant in the last 15 years). In fact I stopped growing autos due to too many herms wasting my time, money and effort.
Decisions, decisions! Good luck, whichever way you go. And I feel your sorrow at this unfortunate occurrence for you.
Hope this helps,.... Organoman.
.... and thanks heaps for getting the extra pictures up, much appreciated.
