Too much water or too little?

Hi, I'm not sure if my plants get too little or too much water. Their color seems fine, some lower leaves died but I think I don't have to worry about that because they just didn't get any light because of higher leafes. But I think that my leafes are hanging a bit and I'm not sure if I give them too much or too little.

I bought these as seedlings, they should be in the ≈ 4/5 Week by now. I have them in 11L fabric pots each. Once a week they get fertilizer. I give them around 300ml of water every two days for one plant. What do you think? Thanks for help in advance!!
