read some grow guides on the internet or buy a grow book, u need to find out what wattage light you have and what kind, because if the lights aren't sufficient you will have lousy buds. Keep the lights on 12/12 cycle to the end from now, have you killed the males, if not, it may be too late from your description. but do it anyway. There is too much for me to explain, you need adequate ventilation for your grow area, are you using flowering ferts? most ferts tell you what the NPK ratio is on the back, look for a high Phosphate content or P content. make sure no light gets on the plants during their dark period. I water the plants when I stick my finger into the soil and it is dry, do not overwater and do not over fertilise. If you do some reading, you should do fine but seeing as you already have the plants you don't have much time. good luck
