You won't get much NEW leaf growth after week 5ish. The leaves that are already there will get bigger though

Awesome thanks mate, Im trying to work out when to inject co2 to the max 2200ppm, I heard in injecting in bloom exponentially increases yeild so Im going to give it a test, just about to start week 4, so will give it a test. Going to go from 400ppm co2 to 2200 ppm straight away the girls are going to be like OMG :)

I havent decided yet, using the LM301b samsung with added 660nm red, I was going to use the lumen meter and go for 40,000 which is about 1000par at the top of the sites, some people have said you can go up to 1500 / 2000par though with co2

You won't really get any new fan leaves after about 2-3 weeks of stretching. After that you will see sugar leaves grow close to bud sites and out of buds. The fan leaves will get bigger and bigger if the plant is healthy. You can cut them or remove select ones if you feel you need the air flow. But remember leaves are your plants energy source so don't be fooled into removing them
