Auto CBD seeds run on an internal clock, and a week lost to transplant shock in the first month is a week off the final size, since the plant will flower on schedule regardless. Sowing directly into the final pot avoids the problem entirely. A comparison of autos started in cups and moved against autos sown in place is posted on https://calmcbdseeds.com and the difference in harvest weight was about a third. Photoperiod plants forgive the move, autos simply do not.
