WLP001 at cooler temps

I used a starter of WLP001 in a semi-rye beer that I fermented at about 65 for 2 days then brought it down to 60 for about a week. I plan to raise it to 68 to dry hop for a week. Is that low temperature going to be a problem?
The recipe called for ECY-12 yeast which I couldn’t get but I wanted to try to mimic it as best I could with 001.
Thanks

Lots of brewers use this yeast down below 60.

Thanks, I was worried because their website said the optimal temp was 68-73.
