whats the best way to switch from veg to bloom nutrients

this will be my 2 time doing this. the first time i went right to bloom from veg. this time i was thinking putting the plant on 12/12 till it shows sex then switch to bloom. anyone else have anyways of doing this?

There really isn't that mucg difference in the nutes, switch when you want. Most hyrdo growers change when they clean the reses out. VV

for first two weeks of flowering continue to use vegging nutes, then change to flowering nutes.

think about it.

you have some choices - after switching to 12/12 - which signals the plant to start flowering, there will still be vegetative growth for the next two weeks.

If you want to "go with the plant" and want to encourage more growth then stay with grow nutes until two weeks after switching to 12/12.

if you want to discourage more vegetative growth and get the plants acclimatized to the bloom nutes faster, switch to bloom nutes as soon as you switch to 12/12.

So you can switch to bloom nutes from the first day of 12/12 up to two weeks after changing the photoperiod.

But whenever you switch to bloom nutes, you should use reduced strength (so if you were at 900-1000 PPM using grow nutes, you'd want your bloom nute PPM to be around 3-400) to help your plants get used to the change.
