What is the best N-K-P ratio for veg and flowering?

A customer has a question and I hope we can get some opinions on it, thanks

“What do you think the best N-K-P you ratio is for veg and flowering?”

For veg anything with a ratio of 1-1-1 to 5-1-1 if they are autoflowers get some food with a ratio in between like a 2-1-6. Flowering early stages something like 4-8-8 for early flowering will do great and about midflower some thing such as 10-15-15, 10-15-25, or 9-58-10 would work well
