Help with sexing:) oh bebe

As a newbie, I too am having problems determining a male from a female. I have a veg area and a 12/12 area which is totally dark. It has been 15 days since I moved some over to 12/12 and I am finally starting to see some changes. Couple more questiions -

1) How quick does pollenation happen? Is it something that happens before I can even see the so called balls?

2) These are a mix of white widow and ice femmenized seeds but it's 99.9% garunteed, how often does that .01% happen?

3) I have 4 clones that have grown roots (yoooohooo), first try all took, not that hard (hope i didn't speak to soon).

4) I am running 6 4' Flor Tubes on the sides of the plants and a 150HPS above, is this recomended for 4 - 6 plants (flowering) or should I switch it around?

5) Should we trim the shade leaves off when you switch to 12/12, someone told me that but I wanted to make sure.

Any comments are appreciated... My next post concerns my next set of seeded ice plnts... They have been under 24/24 for 28 days and they almost look like they are flowering, please review and comment...

Yall have a blast, I don't do the stuff anymore but man I love watching them grow....

Something happened

My spelling and grammar sucks and I canâ??t seem to upload pictures, mabey I should start again Have funâ?¦ A couple close ups of my flowering (male or female?) and the 9/11 ice babyâ??s.

Question;
The new ones almost appear to be flowering, is this possible? When should I move them into flowering? Is there a rule of thumb?

Sorry to be a pain and I appreciate the help.

99.9 = 1 in a thousand

In response to the rules of nature:) Thanks for the response and to clarify, I am veging the two but they almost appear to be flowering? They are the green pic's at the bottom.... They where planted on 9/11 and they are ICE (so they said)... If so, 4 out of 4 germinated....

When should I move the two greener pic plants into 12/12?

Love the group and forum....
