Hey Mate,
Well this is hard to say via distance. But due to that the XS2000 seems to be a Monster in terms of ppfd and power the chance is quite high that the lights burned a hole in your lil' Damsel. Did you Spray during lights were on?
I have to admit that I haven't seen the XS2000 performing live but I would be careful though. I'm using a Sanlight Q6W (215W)first Gen. and I have to have a distance of minimum 80cm to my seedlings, otherwise they'll burn.
Hope this will help a bit, good luck and happy trails for the rest of the way 🤞
