Hi, you're definitely giving too much water; the plant doesn't seem to have other issues. Unfortunately, I would need more information to help you. I usually give one liter starting from the fifth week every 3 days or so, but it obviously depends on the case.
To be sure about watering, check the weight of the pot; if it's very heavy, then wait until it lightens a bit. Lift the pots before watering and after to get an idea of how it should feel. You can also stick your finger in the soil, being careful of course, and if it feels damp or wet, then wait until it feels dry at least 3/4 centimeters deep.
I recommend calculating well when to switch to flowering if it's a photoperiod strain because they tend to stretch a lot, and you might have space issues later. Good luck :)
