My lighting consists of 3 T5's and one LED strip which has helped me grow some luscious plants. The T5's are about 6 months old and are run 8 hours a day. I've noticed recently that my background plants are no longer growing vertically but are now starting to 'lean' towards the foreground. Does this mean my T5's are getting old and aren't putting out enough light anymore?

Thanks!
