I stop the last 2 weeks, the plant stores nutrients in the soil and leaves so basically you get 2 free weeks of feed by only adding water. About a week in the soil, then it starts taking nutrition from the leaves. It basically is trying to imitate as if it was grown outside naturally. The idea is 1. Save money on nutrients and 2. Stress the plant into thinking its death is coming and produce more resins/stink.
Ask yourself this, if theres no difference at all then why not flush? Why keep mixing nutrients till tje end if it makes no difference? The only logical answer is to sell you more nutrients
