When to stop veg nutes and start bloom nutes?

@Larkinvt as soon as she is putting out pistils and developing those early flowers is the time to switch nutes

Wait until there are small "budlets" before switching to bloom nutrients. I usually stay with grow nutrients for the first 2 weeks of flower, before changing to half bloom and half grow for the next 2 weeks, before changing finally to straight bloom nutrients through until harvest. This seems to produce the biggest blooms on plants that don't exhaust themselves and end up a sickly yellow by harvest time. Have been doing this for 25+ years and swear by its effectiveness. I also only use half to two thirds strength nutrients too. Hope this helps, Organoman.
