Aqueminianswered grow question 3 years ago If your going to switch at week 4 of vegetation. Then start LST early and stop when you see pre flowers forming. Don't switch to flower nutes until week 4 of flowering. Or on week 4 of flowering do a 50/50 mix of grow and bloom. Plants still need a lot of nitrogen during the beginning of flowering.
Check out my OG Diesel Kush autoflower diary to see how early I started training and when I stopped.
You'll see it's a big plant even tho I didn't give it enough nitrogen before flowering and shes lime green now. I'm really surprised she's doing so well.
