When is Deload Week Required?

Hi all, just got back into the gym this week after a 10-day break due to illness. I am on 531 routine.

This week, I did the 1+ rep week with the "not doing jackshit" template.

I won't be able to go to the gym for the next 5 days because of other commitments.

I am wondering for next week, should I do the deload week as scheduled, or I should just proceed to the next cycle of 531, since I just took a break from exercising?

Thanks!
