Hello.i am growing some WHITE WIDOW auto flower,ran lights for 20/4 for veg,,do i keep the lighting the same,or do like normal and go to 12/12 when they begin to flower,or since they are going to flower with any amount of light keep the lights on for longer periods of time.also,i have 4 plants,3 in soil and they flowered about the same time give or take a few days but the 1 hydro,DWC system, that plant is much larger but weeks behind the plants in the soil,is there a reason for the late flowering with the DWC.Thanks
