@Highlaing, I used a coca cola cup of 330 ml so my numbers kind of guesstimate.
I started out with half a cup per day, which were fine at first and upped to 2 cups (two daily feedings) at week two, but struggled to keep it hydrated.
I just took a quick look at your diary, and based on my very limited experience , I would state this:
Your plant looks healthy, keep doing what you are doing until the leaves start hanging slightly, then up the water.
Also be careful when comparing to diaries like mine, as I grow in coco, and you use soil. Most likely you would get root rod if you were to replicate my coco feeding schedule (and algae, I had to use some soil in the top edges, and they are growing algae as it's always moist).
I believe soil should be watered when it's dry about a knukle down.
Edit: check out my day 12, to see what underwatering looks like
