Ask a Bowman Thread.

Would it be more beneficial to start the blood build earlier when it's easier to level?

Or would that severely hinder my damage?

Just curious, cause I'm quickly approaching the 100's now... I hope to get as much info as needed in order to make my ranger a decent character that i can explore the maple world with =P

There's nowhere you train that needs you to have more hp at these "lower levels" up till transformed newties and skeles, which you wont be training on till 10x/11x so washing earlier would be somewhat wasted (as that's your goal for washing: those two training spots).

The later you wash, the less damage you lose out on as the higher you get, the more dex it takes to make up 1 weap atk, meaning essentially you're losing less wep atk per point you put into hp.
