I made the mistake of starting my seeds two weeks apart(couldn't afford the whole batch at once), and now I have some plants two weeks ahead in veg than the others. To make matters worse they're sativas and getting damn tall(basically ready to put into flowering soon). Can I safely slow their vegetative growth so the other batch can catch up and flower them all together, and if so, how? Due to space/financial constraints, I can't afford to set up a clone/veg room now, so moving a batch to a different room isn't really an option.
