AsNoriuanswered grow question 2 years ago No, you can start to mix, keep veg nutes, but add 25% of bloom. Next week 50,75,100 on fourth, it will be 3 week of flower to them.
And from next week reduce veg nutes by 25% each week.
Math will say you use 125 of dose, but its most simple explanation how easy transition works
By week 5-6 off flower - all nitrogen or veg nutes should be stopped.
Happy Growing !!!
