Odd; 0% is supposed to be exactly that, and there is no automatic 1 million people growth per turn on such planets (or growth via reproduction).

The only way to increase growth on a planet is to build Climate Control Facilities, which will *slowly* increase conditions... and that will only work if you haven't scrapped your ER too much. Oh, you could also try to make friends with an organic race... or start capturing planets belonging to said organic race.

Otherwise, you will have to be very careful with population management, only putting 1 million settlers on planets not used for Colony Ship building, and ferrying settlers around for those SY building Colony Ships. Fun!
