induing flowering

I'm using aeroponics and gh nutes. Do I switch lighting to 12 12 wen I chang my nutes
to induce flower or wen I change my nutes to full flower nutes or is it another time?
I'm a first timer so can someone who knows help me out?

start your transitional stage of nutes when you change your lights schedule...it should be on the label

Yeah when you switch your lights change your res and use flowering nutes some nutrient companies direct you to use both veg and flower nutes for the transition.....I just use flowering nutes when I throw my girls in the flowering room....

you can induce flowering when your plants have gotten strong and healthy..when you flower depends on how big you want your final plants to be .. if you flower right away you will have little plants .. if you want 3 foot plus plants let them get 12-18 iches tall then flip em back ...or even bigger i have saw plants that were 6 foot tall still in veg waiting to go outside as soon as the weather got warm and the light season got over 13 hours of day light ..

sea of green with many small plants flower as soon as they get a nice big root mass ..

good luck.
