Nirvana Aurora Indica

Week 7 everything is going smoothly. I am continuing to train both along the trellis net. Aurora 1 continues to grow at a faster rate than Aurora 2. Aurora 2 is also showing a little bit of nute burn at least as best as I can tell. I'm guessing this is do to the slight overwatering it received last week. From reading online I've seen many different opinions given on how full you should get your screen before switching. I've seen suggestions saying to wait from 70% to 100% full before switching. Aurora 1 is already almost filling up her entire space and I'm afraid if I go to much longer before switching she will outgrow her space or at least make the canopy difficult to keep even. Kind Soil says a 3g pot with 3lbs of Kind soil will feed a plant for it's entire cycle with a 2 month veg time. I have two other Nirvana Wonder Woman ladies in the tent that are a week ahead of the Auroras. Taking all of this into account I'm planning on switching to 12/12 the end of this week. My hope is that I will be able to fill in the rest of the net during the stretch and I'll be able to keep the canopy nice and even.
