Hermaphrodite?

See the hairs? Those are "pistils" = female, but that stuff grew long before your stress, so it is irrelevant. You'll want to monitor closely 7-14 after the stress. Sex organs don't grow overnight. You won't be able to see them for quite a few days and may or may not be able to distinguish that soon without dissection and some decent magnification.

Purpling is often considered a tell-tale sign of phosphorus deficiency, but purpling is actually a response to any stress. The plant is not producing chlorophyll in those areas, so the underlying purple pigment comes through. How is your soil aeration? Phosphorus likes to bind to oxygen in medium, if there is oversaturation it restrict uptake dramatically. Too much calcium can also cause p uptake problems on ph above 7 I don't see any bananas.

Hey there don’t worry at all those are not pollen sacs those are just some large calex most plants will grow a calex right there but some plants are smaller If you were to have pollen sacs grow at that same location witch that is a common location for a pollen sac to grow on plants that come from feminized seed but that’s not what’s happening to yours In the future if you ever see some small pollen sacs grow lower on the plant and not coming from actual buds you can just pluck them off it takes a couple weeks after they start to grow b4 they release and most the time they have 0 pollen or close so even if you missed a few it would not barley make any seeds maybe a few seeds here and there like 20 seeds in the whole tent or something When I have a plant that grows a few pollen sacs I I will pluck all the pollen sacs but 1 or 2 and I will keep an eye on them when they are getting close to release they start to get like a light yellow color and you can see like lines on them like a folded up flower is what they look like b4 the release at that time I will pluck them off and pop em open and sprinkle the pollen out it will be just a few little yellow specks of dust I will then take that pollen on my finger tip and rub it on a bud site in the mid section with good lighting from the best plant in the tent then when I harvest I have a few seeds from the best plant in the tent and they will be feminized

No. Don′t worry about a thing 'Cause every little thing gonna be alright. The balls (even if they are bananas) look like they can drop a load and release stamens, not good described...
