First NL Auto

I am a bit confused, it's flowering, but it's slow. I am sure temperature doesn't help, I gave her 1 liter of water every 3 days, supplemented with 1ml of biobiz biobloom and 1ml of biobiz topmax. I also had to defoliate a bit, it's in a 3x3 tent with another nl, a bit smaller, but still bushy.
