light change advice

hi iv got 3 week old superskunk, under 1000watt light. and there doing really good, some shade leaves are as big as my hand. (should i remove them cause there blocking the light from the newer growth. also how old do your babies have to be before you change the light cycle. thanks

Hey, i wouldnt take any leaves of if they are healthy myself, and you can switch to 12/12 any time you like really.
