alternating nodes are a sign that the plant has reached sexual maturity and is ready for flower. you should see the nodes start to "stairstep" at maybe 7 - 8 nodes up. Looking at your pic I *think* I spotted alternating nodes. Your plants should start to display their sex within a week or so, with the males showing first. I can help you with identification if you want but you have to show extreme closeups in the node areas. Once you have eliminated the males, you might want to consider cutting clones of the females so that you'll have plants already growing for the next grow, and they will already be identified as female (of course you'll have to put these new clones in another room, on a 24/0 or 18/6 cycle..and make sure no light from the veg area is shining into the flower area). Expect these plants you have flowering to grow up to 3 times the height when they entered flower..have you changed to flowing nutes yet? BTW your plants look really good.
