During this 6 weeks phase of raising the plants behind my livigroom door very DIYish I made a mistake by not checking the soils pH. At this point the soil is newly bought cheap potting soil from the closest supermarket (Penny). It contained fungus gnats and also had a pH 8.2 which lead to early flower of the Tropical Tangie and a shock for all the others resulting in weeks of no growth and visible signs of degeneration.
