Too late to apply for financial aid for UCs?

this might seem like a dumb question, but is it too late to submit fafsa for UCs? I’ve been getting a lot of emails from UCs lately encouraging me to apply for aid, saying how “you never know”. However, I clearly remember marking that I didn’t need financial aid on my UC application so I’m wondering if it’s too late now. (I was advised to say I didn’t need financial aid since UCs aren’t need-blind, but I’m having regrets now.)

Deadline is March 2 so hurry up and apply if you want to be considered for some FA.

The UC’s are need-blind which means that the UC’s do not consider financial need in their admission decisions.
