Not a long time indoor grower myself, but She looks healthy to me, Buthead seems to make note that he has had some years experience behind him so I wouldn't discount his observation, just not sure how he came to that conclusion as it would be a valuable bit of knowledge to know how to see from your plants photo that the ph is too high or your watering wrong.

cool setup ( got a kick out of your light sockets , looks like something I might do )

People learn from your grow keep it going, like to see your progress
