Are you using two different strains?? Its what it sounds like to me.
That is always a bad move.
One might stretch more than the other, one side will be fuller then the other.
Can you some how slant the screen. Making it shorter for the one smaller plants going bigger to the side with the larger plants? I would wait to see a pic to judge if you should flip the lights any time soon.
Damn, ive got 2 master Kush, 1 Bluberry dream, 1 black domina and 2 heirloom bubbas. 4 different strains....I was thinking though, instead of slanting the screen how about putting the shorter plants on platforms to reach them up to the screen? Ill take a picture as soon as I get home and post it on here
