Hey guys I've been growing for about 18 months and recently switched from cfl's to a 400w metal halide grow bulb... I think my vegetative growth is behind for this far into veg but not quite sure because I've been using clones.. Also I've noticed either light burn or nute burn and was hoping to get a little advice... Any input is appreciated
