First try indoor - Mephisto

Day 27 Tried LST gently(my own opinion) on some girls , watering once soil seems to be dried . One time water only , second time adding JIDB basic nutrients(grow + flower + enzymes) I'm using filtered tap water , which stay at least another day before use - PH is around 6 , PH of nutrients is 5.9 One girl has yellower leafs - not sure if it is due issue with nutrients or with water(less or over) , Others looking healthy I am surprised how small spacing between nodes is as when I grow some autos in balcony , it was totally different  Also definitely will be using larger pots around 15 L next time. But I am aware that it is my first try , to see if my setup will be working at all and i can learn a lot from this round.
