Greengregor Pots were too small, repotted from 12L to 20L, due to the weather issues with humidity (up to 80% at night) - dehumidifier is now set to 40%. Light power set to 100% (300w).
@MrGreenBean420, yeah :) once a week per plant about 1 liter with nutrients, the rest of the week just water. That was also the last time with nutrients, from now on just water for the last 2 weeks. I stuck to the chart, is 4 too much?
