First time no soil! Gorilla Glue Auto

Week 5 and we see the vivid signs of flowers bursting their first tiny particles. I am seriously panicking because of somewhat difficult growth. Friends and growers were reporting stunted growth all across different conditions because it got suddenly very chilly in the city and it was hard to maintain the usual and favorable temperature/ humidity levels. It even snowed in the city and its surrounding mountains. Yes we grow indoors, but outside weather affects anyways. I observed that small ventilation fans inside the box felt pretty cold. I checked the stem once and it was freezing cold, like it was in the freezer. I am struggling with these variables to solve the equation. I feel not so close yet. I just pray to the Gods of high to pull my lady up a little bit and give her some strength. So I had to get creative and make the growing process efficient (which I would not do, should she has grown to the level expected), and also does not stress her even more. So I decided to give more light and air to already growing branches, which until the end of the previous week were overshadowed by a rich ventilation foliage. I ended up with a pretty decent LST result. It almost looks ideal. I attach the picture where buds to be are ideally arranged under lights. These lines look like SCROG. One day I should definitely try it. I was even thinking, if the growth starts finally, shall I bend the main stem towards one of the sides to allow upper, newer branches to grow vertically to the lights and then allow the main one to join other in their thriving to the light source. let's see, this is only beginning of this critical week.
