Update 2/2
I went ahead and put all four into flowering as I'd like to start fresh after this grow with good fem seeds. However, one of the little plants has shown female. 3 females out of 4 and from bagseed is pretty lucky, but I don't want to go through the guessing game again. You'll notice I've got better pics this time around. I'm not sure how much that's going to continue as I'm borrowing the camera from the old man. I've been adding some flowering nutes, but just lightly. I think the flower nutes still have a little too much nitrogen as you can see some curling going on. I'm seriously thinking of just going straight water just to avoid the burn and curl as I can't seem to avoid it however light the nutes are.
I'm thinking harvest will probably be around the end of March, but I'm going to invest in a good magnifying glass and just hold out until I've got about 50% amber on the sticky.
