oh yeah, big changes, lol, I raised the lamp to about 9" (just to see if I could get a dramatic change) and the next day, I noticed the lower leaves were yellowing. But the yellowing did not get worse the day after, and guess what?!? New Growth! haha, also, I've been noticing that one has stayed low while the other is shooting up. They are both exactly 2 weeks and 6 days old, but one is only 2" tall, and is just kinda laying low and developing a canopy, while the other is 2 1/2", and the stem has split at 1" into two stems, or I guess you could call it "two colas".
