DAY 1: I have removed some bottom small and not enough-lightet branches and also made some small defoliation to increate air circulation.
DAY 3: Again some minimal defoliation to increase airflow (since LST which I made is not ideally). Additionally, next watering! Since last 6 days, today was the first day when I noticed little drop of lower leaves due to lack of water. I would say, it is a very good result after using self-watering base. I will also add some clay pebbles on the top of the pot, also reducing light slightly to reduce temperature and water consumption. Next photos tomorrow!
DAY 5: Watered plant with 3L of water with nutrients. Additionally filled basis and everything else with totally 14L of water with pH 6.3.
