Solo SaaS builders — how do you actually split your time between building and marketing?

I've been heads-down building for the last few months, and now that I'm past my first launch I'm hitting the classic problem: every hour spent writing code is an hour not spent talking to users, posting, or actually finding people who need what I built. For those of you doing this solo (or with a tiny team) — what's your actual split? Is it a strict schedule (mornings = build, afternoons = marketing), or more reactive depending on what's on fire that week? Has that ratio shifted as you've grown, or gotten more lopsided one way?

Trying to figure out if I should be spending less time in the editor right now, or if that's premature.
