Hi!
No, 60% is good for the vegetative phase.
You don't need to adjust it specifically for your plant that started a bit later.
Temperature is also okay👍
Keep growing!🌱
Anywhere between 50% and 70% is fine in my experience, I've got seedlings that are 1 week old and have been in 40% humidity, not ideal but not, and never has been, an issue with growth.
