When's the latest I should be pulling out males?

I live hours from my plants. I went about three weeks ago, and didn't notice any sex signs. Since then it's been raining nicely, so I haven't gone to visit since. The best time for me to go again would be in a week. I can also go tomorrow, but it would be extremely inconvenient, would I be okay waiting the one week? Or will my females suffer because of it?

I live on northern NY state. Much thanks!

if u go in a week u should be able to tell the sex. we live in the same region and most people here have just begun sexing in the last few weeks, u'll be ok

Any time before the flowers open

I suppose my next question is...what date do flowers usually open?

as sooon as you see big nut sacks lol
