Too little water?

If you water every 2 days, the soil will not dry out. You don't need more water.

From the pic you added it doesn’t look like it’s overwatered at all. Your leaves are large, but not really droopy from being overwatered. More from just their size maybe. I overwatered my plant once and it’s leaves looked swollen and fat on the edges, but kind of wrinkled toward the middle. Yours don’t look like that. I tried to add a pic here to show you, but it wouldn’t let me. If you’d like to see it, go to week 5 or 6 of my Dark Star Diary and take a look. I water when the soil in my pot is dry down to a knuckle deep. The period in which this occurs will change as your plant grows. You will go from feeding/watering every 3-4 days to watering every 1-2 days. You really just need to see what works best for you. As far as amount to feed; I feed a gallon of water with nutrients every time, and then drain and remove the overflow water so that the plant doesn’t sit in water drowning. That was my mistake, but since removing the excess water I haven’t had a repeat of overwatering or the symptoms associated with it. Hopefully this will help you make appropriate decisions when it comes to watering your plant. Best of luck to you and your plant.

I think that's too little. If they're 5 weeks old, you can already start watering until runoff (around 2.2 liters of water for 11L pot) and then in a couple of days water just the top surface with 800ml to a liter. Then repeat. Only water when 3cm of top soil are dry and only if the pot gets light.

Wann hast Du zuletzt gegossen und wie viel? Ich habe einen 8 Liter Stofftopf und den muss ich spätestens am 3. Tag giessen. Der Boden wird schnell trocken. Wenn Du jetzt vor 2-3 Tagen gegossen hast, dann würde ich heute vorsichtig durchgiessen. Bis es unten raustropft. Du kannst Stofftöpfe nicht übergiessen.

Get yourself something to monitor the soil moisture they have been a life saver for me and you can pick them up cheap
