I am having the same problem, im 12 days into Flowering & nothing so far

Although I have these weird growths starting (3 days into Flowering Cycle) on one side of my nodes not both & they have barely grown at all. They look like New Growth even though there is already a branch.

I think I have a High Sativa strain but not really sure, the plant doesn't have an Xmas Tree Shape & it grows fast with long thin leaves bigger then my hand.

-Im using 15-30-15 Nutrients with Micro Nutrients.
-I had my plant on a 12/12 but read that Sativas may need longer nights so im on a 11(light)/13(dark).
-Strain Unknown
-My plant is 9 weeks old in 2 days.
-Im growing from seed
-My lights are 2/250W White Fluorescents with 1/20W Grow Light.

I just hope I don't have a light leak... but then what are these weird growths? & why are they only on one side of my plant?
