Erster Indoor Grow

I moved the 4 Autos into the tents instantly. The height of the plants Refrains to the biggest wich ist the northern light Auto. Almost all of the Plants have hanging Leaves, although im watering right. Maybe its because of humidity. Sometimes its under 40%. Or the ph. Ive ordered a ph tester to look If its the Problem. If Not it could also bei larvea that got in there because the plants stood in free air and not in a tent. Need some advice right there. All of the Autos are also 3 weeks older than the Apple fritter auto and Coco Haze photo, where the Haze is still in vegetation. The Apple fritter is starting to bloom and it grows very dense and bushy. But now the Stocks are starting to rise Up. I will Take some extra detailed photos tomorrow to maybe get some precise advice from yall.
