Plants starting to flower. Female? What do yo guys think

This wednesday my plants are exactly 2 months old from seed and I switched to 12/12 12 days ago (11 days since switching to an HPS bulb) and I think they are definitely showing signs of flowering and female. What do you guys think? I know its hard to see sometimes under an HPS ill try for better pics later. Also about 4-5 of my plants lower leave are really starting to droop. Could that be from lack of light since they are getting large and filling in? Maybe I should get a few side lights. Thanks for looking
