sounds like a true hermie,coming from genes,not stress.It'll throw out and grow balls whatever you do.You can remove balls by hand but there will still be a lot of bananas or sacs that can't be reached.Up to you mate,toss it or keep it but you'll most likely have seeds off other plants too.Quality won't diminish hugely but this one looks like a bad genetic.This is why I hate barneys.I've had stupidly non sense plants from them.Commercial breeders always do this.Mix crap seeds with healthy ones and sell.I'm avoiding barneys.Just keep in mind.
@HighRoller909, thanks mate I appreciate your quick reply. Knowing that it's genetic and not stress related makes me feel better about my gardening haha. But still, I will remove it - I'd rather 4 plants without seeds than 5 plants with seeds.
@sloppyjohn, your ph range is 5.5 to 6.0 for veg and 6.0 to 6.5 in flower. The higher ph in flower allows for better p and k absorption 6.0 to 6.5 in veg of 5.5 to 5.8 allows for better N uptake. Plants don't need much N in flower. It will pull from the leaves if it needs more N.
nice you should fully cure over at least 3 weeks. and then see the high will change it wont turn you melancholic anymore. its because your weed isnt matured enough.
