White Widow Autoflower - first grow

Ok.. Houston we have a problem! Again sorry for the light being on as they pics were just for my viewing and I had not planned for a diary. The week before this picture is when I started to figure out I was going to have a space problem! a 2x2x4 tent is not going to hold those 2 plants plus my tester. By this time I had added a carbon filter to my set-up for the growing smell and my reduced airflow from my crappy 100cfm fan was causing the temps to rise up to around 80 degrees. All three plants were now 15" from my light so I added the net to try and hold them down as the 2 main plants were now starting to flower and stretch like crazy. My tester (in a half gallon pot) was just finishing stretching at this point. Also at this point I had to take a business trip for a full week. I enlisted my son to at least water them every other day, but he didn't touch the plants besides that. I needed a new plan. 1) bigger tent 2) bigger fan 3) more light for the bigger tent. So I ordered a 2x4x5 tent along with a 400cfm fan with a dial to turn it down (I wanted more than I needed so I could turn it down versus not enough). I added a second light of the same make and model I already had. I know its a cheap chinese light, but reviews were good and it had done well so far. What will happen to the 2 main plants during the next week?
