nutrients help

just put my plant into flower and was wondering how often to giv it nutes on a 2-2-6 also since i got my first "9 leafer" each leaf above it has 10 or more on, the most is 14 is this normal?

thats good to have more leaves, from what I have read. What medium do you use?

just some compost i got off a friend it was nothin special any ideas on how often to feed
