3-2-1/1-2-3 is just another option that is being used. Advanced nutrients and GH do something close to what I posted...I just tweaked the formula a little as per my own observation.

I used 3-2-1 in my 1st grow, back in the day, but there is no need and you would have to tweak that too. that is alot of nutes...Also
think of the world when you have a question...common sense...When does the sun turn off for 24 hours?:smokin:

If the sun doesn't turn off, then why would you turn off your lights for a day...Just change periods, and change nutes...If anything is different at transition, then it is the fact that some growers "flush for a week at transition. peace
