Nope. Plants will adapt to the amount of light they get. Sure, the more light the better, but a plant will grow leaves to get more light and use the leaves that get less light to store energy for flowering.
If you really want some leaves to get more light, try Low Stress Training (LST) or pinching/supercropping or even topping (yes, that IS different than pruning)...
oh... and Dopeman...Now you know everything? (?!?!?) that's a bold statement, don't you think? Don't be afraid to ask questions, LOTS of questions. Something new will come up everyday, whether its sickness, abnormal growth, or just questions. Either way, this is the place to ask questions and I hope that you'll use this forum to its fullest, whether to ask for info, or dish out some knowledge.
peace.
