Pyrethrins and Neem oil... how late can you apply them.

I've heard that you must stop neem oil at the 3rd week of flowering. So, I'm guessing as soon as you start getting buds/calyxes you should not spray? I had pistils in day 1-2 of flowering on many plants, they are just starting week 3 and I see alot of pistils, but not any calyxes and buds forming yet... soon I'm sure!

Can you still spray neem on the lower fan leaves of the plant throughout flowering? That seems to be where spider mites start anyway. I still might be a little leary that I'd inadvertently spray the buds.

Now pyrethrins... how late can you go on those? On the FF Don't Bug Me spray (which is pyrethrins) it says you can basically spray right up until harvest. I know these breakdown pretty quick. Could you spray these up until like 1-2 weeks before harvest? Would it affect bud quality if it got on buds a couple weeks from harvest?
