When I first got my TSW2000 I experienced some light stress that it expressed itself as droopy and twisted leaves. When my plants were in the vegetative stage I had my TSW2000 dimmed to only 65% at 28 inches away from the canopy after noticing this. After about 3 days dimmed the droopiness disappeared. I believe since you have the two lights next to each other the canopy is receiving a lot of lumens there for you don't need the lights to be very high.
Also another thing that can cause droopiness other than light stress and under / over watering is cold nights. Vegetative plants especially indoors do not like the cold. But other than that your girls are looking good growMie! Nice work! ✌️😎💨
