Just to add to this topic....I recently accidentally broke the main tip top on a plant that had been in the flower room 2 weeks when I transplanted to a larger pot. Yes, growth did slow a little...sort of. The bottom caught up to the top and the main top is now growing 6 main colas, all equivalent in size, no nanners showing at all. No stress other than that issue on this plant. Actually it is looking kinda cool, normally I don't top this plant, and if I did it would have been in veg.
