Bright lime green on all new growth

Hello I just flipped my plants I had just fed them half strength sensi grow+ half strength sensi bloom with some cal mag total ppm was around 575 with ph 6.6.
I let them dry for a day then I had them in 24 hours of darkness before the flip it went maybe like 36 hours darkness because I forgot to switch on the actual light. But I don't think this is light related.
If you have any suggestions or advice I would greatly appreciate it!!

What are you growing in? Has the situation changed now that you have your lights back on?

It looks like an iron or sulphur issue, could just be the 36 hours of cold and dark that did it.

The light growth is what came out during your dark. It will darken with light.
