When to change nutes for 12/12

Im nearly ready to change to 12/12. Do I chnage from grow to bloom nutes the same day as i change the light? Thanks, Dorian.

I think you should wait 1 week before changing veg nutes to bloom nutes.

Wait for the advice from other, more-experienced board members.

I know that Zandor uses a bloom 'booster' to 'kick' the plants into bloom... but I trully don't know if it's when 12/12 is switched, or if it's in the 1 week later nute change.

Hope this helps,

i'd wait untill some buds appear ...then drain the system ...then start on the high phosphorus nutes ...but ask around!

You can run half and half for the first week of 12/12. You can run veg the first week won't hurt. If you have an additive like bud blood you will mix that in the first week and then go to big bud. In the first 2 weeks they are still vegging. Ecspect a good bit of growth then.

Thanks for the help guys. At the moment i'm not using any additives simply cus i anint got the money to. Im usihg anvanced nutrients 2 part.

I switch the lights to 12/12 then 2-3 day's later I switch the nutrients out to flower nutrients and then add the MOAB to kick start them for the first full week of 12/12. In truth I end up changing my nutrients out every week they just drink up that much that fast. It's easer to change them at that time and give fresh nutrients for me anyway.
