Just wondering when I go from 12/12 to a 20/4 light cycle,do I change my hps bulb back to the vegging bulb or just leave the flowering bulb in to get the plant growing again

I would switch to mh also put my lights on 24/7 till you see new growth. That way there is no doubht to them it's reveg time. Once new growth starts you can drop down the light schedule.

...you can use either light....both HPS and MH will veg and flower....but if you want to go, "text book," a vegging plant wants more blue spectrum.
