Waiting that long to start your nutrient cycle will not give the plant it's maximum strength going into flowering. I would argue that growth (vegetative) nutrients are most important as they build the platform for your budding plants, if stem structure is insufficient the plant will not be strong enough to support heavy budding.No you wont need any nutes until like the second week of flowering...then give flower nutes.
Yeah well I would argue too espacially if he said he will veggie only for 3 weeks or less...I haven't had plants that would need nutes after only 2,5 - 3 weeks in veggie. If stem structure is insufficient, he will have to support the buds...that's just what it is if he wants to veggie for this long. Good luck!Waiting that long to start your nutrient cycle will not give the plant it's maximum strength going into flowering.

Start your nutrition on the third week of vegetative growth and maintain for a couple weeks before you switch over to your flowering stage. Shoot me a message if you'd like more information on nutrients and cycles if you'd like. Good luck mate, good post S&C
