Hey brock, thats very interesting.... This year it did not happen, cant explain it, like much of the universe lol... I do t have any bracon near my grow area, but there is alot in the general area. Fascinating !Very interesting. I grow autos outdoor with photos and have done for year's and never had this problem. I am not saying it cant happen though. lots of factors can and do cause premature flowering. You have ethylene for example. These are produced in low levels in cannabis as a rule and can not only produce early cropping but hidden hermaphrodite tendencies. Theirs also chemicals that are made in the roots and by root restriction can reducing vegetative period. Then you have the native plants pumping gasses out all over that can effect your plants flowering. Bracon for example produces a growth slowing hormone that stunts plants around it and force's premature flowering as a survival response. I believe the gene responsible for photo sensitivity is Flowering Locus T. It produces hormones based on the photosynthesis cycle of the plant so the actual photo sensitivity is 100% genetic not hormone based that as I said does not mean environment doesn't play a role because it certainly does.
