way too much red light being used here
maybe use light in the 6500 kelvin range(the light color)
or cool white at least until bud
this will reduce the growing internode gap
the gap between branches...on yours fucking huge
a gap of a plant at this age should be about 1-1 1/2 inches you got 4?"
compares to
Rolla J's below which is opposite to you
here he has dominant blue/cool white at about that 6500 kelvin
hence the squat shitty look (srry)
that may correct with 2 monthsd flowering/bud ahead
correct light at the correct time in the correct volume is crucial guys
