Let me start by saying leaves only photosynthisize from the top any light below the leaf surface will only dry it out...You are in need of lumen's my friend it will yellow from the bottom (a nice looking babby) and eventually die. you know a mirror is the worst reflector in the world? a piece of dry wall is 150% better!! loose it and make your wall's flat white and get better lighting or more, from the top! Good luck my brother!
