Your plants look nice and healthy well done, I have 1 suggestion for you since you have one male have you ever thought of breeding it with your best looking females and trying to make your own seeds and stock, you do not have to pollinate the whole female, simply dig the male out and put it somewhere away from the females wait for its pollen sacks to develop, when this happens shake the pollen in a bag or 2 or 3 depending on how many females you want to pollinate then loosely tie each bag over one branch of each female and rub all over the bud, leave the bag on for 2 days then remove, when you come to harvest that branch will have seeds,

I have bred my own seeds and had lots of fun developing my own strains some seeds are good some are less so e.g hermies or autoflowers, but it is very rewarding especially when you get another nice male and female then you can breed those two and keep on repeating the process selecting in and out the traits you want and those you wish to discard bonus is you can create what you want although it is a lengthy process but ultimately a very rewarding one.

All the best on your grow and keep us posted.
