somthing evil munching on my plant??

ok so im growing a dinafem moby dick.
the plant is 27 days old.
my medium is soil and perlite (80/20 mix).
im watering roughly every three days (or when ever its thirsty).
im using bio-bizz nuits.
there are 8 other plants in the room with the same set up.
im growing under cfls.
temp - 28degrees
humidity - 49%
iv had no problems with the plant till now.

now my problem, parts of the leaves on the new growth is disappearing. looks as if its being eaten.
i was thinking maybe leaf miners??
any help would be appreciated as id like to stop this before it turns into a major problem.
if i left anything out just say and il let you know tonight (im working today so wont be able to check back)
again, ANY Help Please.
here are some pics of my problem :

How close is your fan?

can a fan even cause that? ive seen that on one of my plants last grow it was all indoor and i had no bugs. Bump!

I have seen the direct air flow from fans cause it. yes. Over a period of time the leaves whipping back and forth will take it's toll
on the soft tissues.

thanks for the replys guys. i keep my fan about a ft away from the first plant
OO
@O
OO

X

if you imagine each 'O' is a plant and the 'x' is the fan, the '@' is moby dick. (the plant in question)

as a precaution im moving the fan back another 12 inchs and turning to a lower speed.
iv never heard of a fan having this effect. is it relatively common?
P.S. sorry about the bump, this is the first time iv really been able to check back. cant go on this website at work really
