when i first started all i was doing was worring about my bud size or if they were the right size for the length of time flowering. IMO, just keep doing what you are doing and see how they turn out if you aint happy THEN, start changing your approch in short take em all the way to the end then decide.
you need air flow as suggested by the ICer's and your nutes need changeing. its good to fuck up it helps getting at one with your plants by learning there boundrys. dont change loads at once just try one thing at a time so you can see the benifit. sorry to ramble im high
I agree with bigwity... I learned by f'ing things up... and now am on a good track .. thanks to the dedicated folks/articles on ICmag.. your in good hands.. cheers!.. patience is never easy but the reward is always GREAT
