IMHO you have to find room somewhere. is there a closet you can use? or you can really trim down and just start flowering now, thats what i would do. it will get crowed but don't let that stress you ouyt. its okay just make sure it doesn't touch the fan or bulb use somethin g as a cover if need be. that all the advice i can give you at this point other then plant does look like its being watered a bit much. but no hate. good luck on your grow.
