hey man lookign good, i beleave In the vegetative phase 20 10 10 (or 20 20 20 if your lamps are 24h/24h on) but dont hold me to that , and also you can put them into 12 12 when ever you feel like it. but keep in mind that the plant can grow up to 3 times its size in flouring .. and at the rate thoease are growing , with another week of veg you can probly tripple the size of your finished product
all together i say your lookign great man happy growing
