info needed

i grew and harvested last year and now im growing 4 clones of that. i added two other kinds and both looked female neither one had balls .now im 6 weeks into flowering and im getting seeds from everyone. i had a male years back and let it go for a while and its pretty obvious. is one a hermi?i heard light stress and acidic soil can help create a hermi.wouldnt i have been able to see the bananas?

If a hemi you would see them. but since you had a male in there some spores could be in the air. since seeds have started they will grow with them. advices for next time is to clean, scrub, vacuum, and blow out the space were they are at. maybe get a bathroom ionic breeze for cheap to trap any particles in the air. good luck and happy smoking.
