Changing Light Scheldule Gradually ?

recently changed electricity provider.
i now have two different rates. night rate 12am - 9am. costs 70% less than day rate.

My question is if i change light cycle 1 hr per night, would this affect the plants in flower and veg

Room 1 in flower 1 week lights 7pm - 7am
Room 2 in flower 7 weeks lights 7am- 7pm
Room 3 in veg oldest plants 4 weeks youngest 1 week 6am - 12am
Room 4 clone room lights 6am - 4am

i wanna make the most out of nightrate because electricity around here is very expensive.
Any suggestions welcome thanks.

No, but it's easier just to do it all at once.

For plants in flower, extend the dark period to your new 'on' time.

For plants in veg, extend the light period to the new 'off' time. Clones also.

you think i should be fine doing it all at once, already after moving everything 1 hr forward, would much prefer to do it in one go, it will get old real quick changing every day
