Dont worry about it man, it should be enough light, im using 13 watt fluoresent lights and a 250 led light strip with red and blue leds, works better then I ever thought it would my girls are 83 days old today and barely 2 weeks into flowering and their already producing good quality buds all over, plus im using pura vida organics, bloom, and grow nutes at 1/8th strength and they are miraculous thus far, plus its my first grow man, I didnt think it would near enough light but their doing exponentially well, great top buds and their all female from a gamble on a few seeds out of a bag i had, cant believe that there aren't any males, or hermies lol. Good growin, keep the peace.
