Blackberry OG, Mimosa Evo x OP

Flowering day 7 here, this is mimosa evo x orange punch, big plant at 5 feet LST. about 2 ft above dirt level so far. very long lanky and flexible branches. I thought this would be "super compact" like they said, but this so far has really been a Sativa stretcher. The leaves however is very indica. The days are cool and the nights are cold, so it's probably stretching due to that.
