When do buds actually start to show up on the marijuana plants?
After you force flowering, the initial signs of change occur with the slowing and eventual cessation of vegetative growth. This generally occurs with a 5 to 10 day period. The marijuana plants might still produce growth, but it won’t be the same as they are now in reproductive mode.
Flowers will appear within the first two weeks. For plants that are three months and older, the initial inflorescences will show up a couple of days earlier. Marijuana enters into the flowering period when you shift the light cycle to 12/12.
Pistils show up at the node where the leaf connects with the stem. Thy will also start growing at the tops of the plant. The buds generally start ripening around 6 to 10 weeks after you started forcing. Some sativa marijuana plants can keep growing vegetatively even while they flower.
