Hey Gandalf, I see you had some issues with overwatering as well. This was huge issue (along with poor quality soil) for me on my first grow. It was very hard for me to find the right intuition for what is enough, so I will try to help here but please keep in mind that I'm still a newby myself.
For the first two weeks i found that about 10-20ml per day is the ballpark. I use a syringe to top up and only water again after that is dry. No nutrients for first two weeks, the 1/4 of manufacturer recommendation from week 3.
From week 3 I start to add much more water in a single session (ballpark of 400-500ml). My goal is to saturate the pot and get runoff. But then it takes a couple of days to dry sufficiently before watering again is possible. In breathable pots with heat of sun in day time that takes 2-3 days. So still averaging below 200ml per day in 10l or 20l pots. You have smaller 5l pots and still doing 300ml per day for indoor grow so it might still be a bit much.
Also, you don't mention what type of lights you are using but do say that light distance to plants is 90cm which seems a bit far for even high wattage led or 1000w hps bulbs. (based on guidelines at https://growweedeasy.com/how-far-grow-lights. (don't take my word for this but may be worth seeking expert advice)
