8 Ball Kush...First grow (medicinal use)

So I've ended up missing a week with my diary....I think, I've completely lost track of the ages of the plants due to been admitted to hospital for chemotherapy and stuff. Anyway, I'm certain I'm on week 4 now, the girls seem to be doing just fine and are rapidly on the rise. My only concern is the left plant has a few yellow dots on the leaves, I'm not overly concerned just yet. Ive topped and started lst with them, over the next few days I'll probably introduce some pipe cleaners to them to help them grow out a little more. I'm giving them around 1L a day now, and I'm not getting any run off....should I give more until I get run off? Am I giving them to much? They seem happy enough. Any tips welcome 😊
