I really wonder about your "hermie" only 5 days after switching your lights. I usually don't fully determine sex until almost 14 days into flowering. Because some females may look like hermies but it isn't pollen sacs it is actually swollen calyxes and they grow out of that stage. Give your babies more time male won't release pollen until 3-4 weeks into flowering anyway so you have plenty of time.

On another note your plants look like they have some seriouos heat stress, probably due to the fact you had 1600w's of light on two plants. I'd go down to just one 600 or even the 400 cause IMO your wasting electricity. Move your plants away from the lights more. Peace bro
