Is this enough light

i have a 3 ft tall plant from a bagseed of sativa dank and i currently have 104w of 2700K cfl lighting and its day 30 of flowering and i just went and bought a 50w hps. and i just purchased a ballast and ignitor etc and im waiting for it to be shipped. another question, is it ok to add the 50w of hps to this plant right now or should i just keep the cfls? either way im going to have the hps and the cfls. i figure it would increase my yeild by a good amount?

give up some pics.........
