Bit of nute burn, ppm?

Hiya
Heres my 1 month old Jack Herer auto in DWC. I stupidly gave her 570ppm (water about 180) a few days ago and i should know better thats a bit much for a young girl. Im fairly sure its nute burn. So shes down at 450 now but should i lower that further? Maybe a day on just pHd water?
Cheers!

A little heavy on the nitrogen. Should be fine. I’d lower the N next res swap if possible.

Dropped from 400 to 300 (water 180) over a few days, so she is feeding, but not much ... When i look at her as a whole she looks fine, but that tip burn still worries me...seems to be getting slightly worse.
Whaddya reckon, am i good?
