In week 2, I increased the water amount to 500 ml. Starting now, I'll poke my finger into the soil to check if it's dry beneath the surface before I water again.
To support her root growth, I added 0.36 g of Great White (5 g/7 l) to the first watering of the week.
On day 12, my plant tripped over as a result of the lack of sunlight during week 1, hence the crooked photo. I used a bit of soil to fix her into place.
You can see on day 14 that she's already stretching her first three-fingered leaves!
Hey, @gottagrowsometime. I use distilled water from our local hardware store which has a pH of 7. At the time, this was my only plant since I didn't have room for more (yet).
