@Master_weeda, thanks a lot, the seed was gifted to me from a friend and he himself is growing it too and is getting good results! Im with a very good feeling about this plant, will post updates soon!
PS: Your alaskan purple is looking gorgeous, good work so far!
@Dro3420, I’m not growing dwc, my medium is coco coir! The water I use has only about 50ppm, wich is a bit lower than yours, so maybe dont use it at the beginning, use it only more towards the end of the grow when they need more nutrients overall

set ph 6.5 and 60% Humidity wait 2 days without nutrients
