Deficiencies

I water a liter every other day

Just water your plant: 0.4L/day is not enough at all! You should fill the pot of water, let some run out at the bottom, carrying away residue and renewing oxygen in the roots.

Your plants are suffering from nutrient lockout which normally has something to do with which I didn't see listed in your diary .... That's a problem if your not checking it. Flush the plant, then make sure to keep your pH between 6.0-6.5.

Another Biobizz user.....shocking. Sorry, I just wish i had a dollar for every grow deficiency question where Boibizz was the nutrients used. First pic with the speckled necrosis spots looks like Calcium deficiency. Well hell, you have all kinds of issues happening with your plant. Best thing to do in a situation like that is to pH some water and douche out your soil with it. FLUSH! Then allow to dry out till pot feels light, then re-feed according to the week of flower you're in and make sure your pH is correct at 6.2

I woukd say potassium, phosphorus and magnesium are issues. Lights might be too intense as well too soon.
