How the heck can you tell that they are female so soon? The pics you posted on the 19th show tiny little babies (just starting on their sixth set of leaves), it's only been 17days since then. Good Lord I hope that you've transplanted them into their own pots by now or else you are going to lose them. They will compete for nutes and they won't grow too big in such a small pot. The "pot" is also transparent and when the roots grow to the outer edge they are going to be exposed to the light, a big NO GO...trust me, I've made that mistake already. They should each be in gallon pots, at the very least. I have one in a small pot, but that's only for experimental purposes and already I've noticed that small pot=small growth.(albeit bushy) Peace.
