Starvation!
One of your planets in ??????? cannot sustain its population! More organics is needed. 64,694 colonists died of hunger.

This is getting really annoying for me. the more organics I transfer, the more colonists die. Could you please tell me how much organics is needed for 1 colonists to survive, and for how long? Thanx, I'd really appreciate it.

You should find in settings, how much organics you need for one colonist to alive. You maybe transfer some more organics, but they use it and after they die again. You should change production of organics on planet and add more percantage to it.

15 min. of trial and error will find the right setting for organics: my settings depending on the planet range from 13%-20% sometimes a rare planet takes more than 20%

13% is usual.
