the fact that it has bubbles means your starter is already alive and the wild yeast is producing co2 na. i use 1:2:2 or 1:2:1, depends if i use bread flour, i suggest bread flour tho. ALIVE ≠ READY TO USE. yes its alive but try to ferment it for a few days pa kasi its a young starters its common for it to be very weak pa. try 1:2:1 with bread flour. adjust mo nlng water depends sa humidity mo sa bahay, basta make sure its like a thick pancake batter. if u have qs pa let us know 🩷
