that is what flushing is all about...they really do look a thousand times better. Now you should make sure they get 12 hrs of darkness even if they are autoflower. Watch the height as they can stretch so high there is no room between the light and the canopy / tops of the plants. You can tie them over (lean 0 left/right/front/back) if you think theya re going to get too close to the lights (should be no less than 8inch. preferably 12). I would start taking out some of the LOWER canopy fan leaves, not really needed. As they stretch, the upper stems should be soft enough to strat training to grow horizontally. Remember, you do not have to bend them 90 degrees in 1 day...little at a time and they will bend just fine. At the point they are bending, those branches will point and grow upwards and flourish from the light exposure. Everything under that can be trimmed off (never more than 30% at a time, heal, trim again)
