Ludicrous Chalice pale edge

[Brian1f1]

I’ve had this for a couple of months. In about 100 PAR. I noticed this edge is pale. I can’t tell if it’s receding. I guess it could be a growth edge but I’m not confident it’s not a problem. I don’t have familiarity with chalices like this. Does anyone have thoughts on it?

The main body still looks pretty happy so I would say it's most likely new growth coming in. Just keep an eye on it and if it looks like the paleness is spreading to the center rather than outwards then there's a chance it might be bleaching.
