About to flower

Should i change my resivior when i switch my lights to 12/12 or is ok to change the res 1 week after the lights go 12/12.
I ask this question because i know that the plants will grow quicker once the light schedule changes. (initially).Will the N in my grow formula make my plants grow larger than if i were to switch to my bloom formula with more P and K right away. Any and all replys are welcomed thanx

It would be fine if you did that. You don't really need the nute change until bud formation actually begins. The extra N probably won't make the plants any larger but it will make sure you aren't N deficient during the stretch.

Thanx MJ.Do u think i should wait about two weeks or so???Bud formation usually doesnt start for about 15 or 20 days into the new light cycle.Right???

That would probably be fine if you did that. Just switch at the beginning of your third week and it should be fine. This will keep the N up for the stretch and get the pk in right when the buds begin forming.
