Femminzed lowyrder2 issues please adivse

Ok here it goes. I am growing 2 lowyrder 2 in a dwc setup with T5 lights. I planted April 24. The lowryders would not flower and they are huge. so I switched to 12/12 they began to flower but it looks like I have one female and one hermie. I think this was a bad batch of seeds since i have seen people in the past two month having issues with autoflowers not autofloering. My question is should I leave the Hermie ( i think its a hermie since it came from femminzed seeds. ) and take the seeds to see if they will be auto flower ?

fems are crap, sketchy enough on theyre own let alone with auto strands. You either dont have autos, or they arent ready to flower yet.

toss the hermi, unless you cant afford too, but all the seeds will be garbage

The problem is they in a dwc and the roots are tangled. if I chop off the top of the hemmie where I see most bannas will that be a prob ?
