First Grow!!! 12 babies from bagseed with Subcool Super Soil

So now that my room is finally up and running I am ready to start my journal!! First grow so any and all comments are more than welcome!!!

Here's whats going on:
12 plants (bagseed, but I believe they are sativa)
400MH on 18/6
6" inline 400cfm active air
the room itself is 6ftx6ft
NO NUTES...Using Subcools recipie for Super Soil
**When they are ready to flower they will be moved to another room with a 1,000HPS

I started 8 of them in Rapid Rooters, and 4 of them straight into solo cups with roots organic under four flouro tubes.
I have moved the rapid rooters into 1gallon pots with roots organic.

This morning I moved 5 of the plants into the main room under the MH lamp.

**having trouble posting pics...will try again later today

pics of everything thus far!!!

OKay I have been really sick and with Halloween shit just got outta control.....alot has changed(duh). Being that I am a newb i am concerned about a couple things that are happening.

Not sure if you can see but in the first picture there is yellow spot on the tip of the leaf...what am I doing wrong, what do I need to change?

Also a few of the plants have a couple leaves that are....twisting? i dunno what is causing that either....please help...plus rep to anyone that gives good feedback THANK YOU
