And if you found a seed in your weed, and it was a lone seed in the whole bag (or a couple seeds, but not A LOT) then it means it's a seed from a hermie. Most WELL GROWN high grade pot growers, will remove males from the crop, to prevent any seeds from forming. When you DO find seeds, a hermie is most likely the result. Which produces Fem seeds, so seeds grown from them will be female. All my previous advice on the subject applies.
Keep temps and nutes at just the right levels, stress will hermie it, as plants that hermied to create the seed have a more defined hermie gene.
Anyway, good luck with it bro! Looks good.
