Does this look ok?

So I'm new to dwc and have just one plant on the go for learning purposes. I'm about week 4 I to veg and things seem to have slowed right down. Noticing some leaf sagging as well. Any ideas?
Ppm - 1050
Water temp-20°
Ph- 6
About 90watt sunblaster cfls
Using full green plant 3 part nutrient system with hygrozyme

Can you underwater in dwc ?
I've got 2 airstones in about 50 liters of res water so I think I'm good on that end. First hydro setup so just unsure

What is your water temp? My temps would go over 80F in my first system, and that's when I would notice sagging. Your plant may also be acting this way after a water change, when did you last change the res? I would also bring the pH down to 5.8.
