Is it possible for are female plant to start producing seeds with out a male

Well I just pulled 6 plants and for some reason I got a few seeds on most not all the plants. It is way to early for any outdoor to infect them so not sure what has happen. The only thing I come up with is that someone that has a male plant in there grow room. I have grown these plant a few times from clones and never seen a seed in any of the plants. A lot of the buds have on seeds at all but the ones that do have a lot of seeds. Anyway here's a couple of pictures of the big girls

Most likely Hermaphrodites and that is not bad every plant will do that because weed is designed to survive and pretty much depends on wind for pollen to move. Look real close at the buds U may see evidence of a dead male shuck or sack opened, probably lower buds where only ones seeded ... I have a strain from Sin City Seeds that Hermaphrodites when grown inside, Clients of mine love this strain, so I keep it going and fortunately with proper care she does always show male pollen sacks under some buds BUT never goes too far, does not seed and there are basically no male pollen parts in the buds or shake after I harvest ... Draw back is this plant never gets super large buds, is hard to grow and always takes an extra week to mature. So that's my war story BTW they called it Galactic Jack and found a random pic online and I was surprised it is identical. I did get some males from those seeds and cross bread them with another plant and yeah it's want to Hermaphrodite inside ... have a ton of seeds and grew a 3 oz 2' tall bush outside and in so cal in a back yard with very little sun (maybe 5 hours direct) - oh and it did not hermaphrodite. -- & 1 other thing none of my other 4 strains I currently grow hermaphrodite

Awesome plant, and Oliver is right very normal. My understanding is this happens when they're left for too long. The plant essentially freaks out grows some balls and impregnates herself right before she dies.

IMO it looks to me that you my have hit them with a hot feed your leaves are really curled in that's a sign right there. your feeding regiments will differ clone to clone my best results Come from feed water feed water week to week and my results are very good here is a pic of mine at week 3 flower I only had your problems with heat and over feeding imo

Thanks guys some good advice but one thing they are 8 week flowering plants and I did take them early at 7.2 weeks. But I did use some new lights for the first time they were the Gavita pro 1000 de with the Gavita controller. They did seem to make them flower quicker and ripen them a lot faster. I have always used 9x600 hps before and never had a seed in any of my plants well maybe 1 or 2 lol. And I have to admit the buds are some of the stickies buds I have ever produced. But at 7.2 weeks they did seem over done
