I noticed that on all but one plant a lot of the branches are at diffrent intervals on the limbs. Some are on the same but the back left plant thought was a male branches are all even on the limbs.
Sounds like you are getting close to maturity on them. Anymore i don't even start checking until 6 weeks of veg and that is after a 2 week seedling period. So that is pretty close to where you are at with yours. Hope they show for you soonYes middle was up april 1 and the others a week after
