concerns about my speakerbox grow

I started a post a couple months ago and im finnaly about 3 weeks into flowering, my first concern was after i started flowering the bottom leaves on the plant started to die, then my plant grew so tall its touching the light and i have the light all it will go up. All the leaves near the light are a little fried, the buds are little popcorn buds for the mostpart besides a couple of the couple inchers but all the buds are extremely hairy and really no bud to it at all. Ill post some pics in a little bit but dose anyone have any thoughts i was mostly worried about the bud size and if the plant will be ok.

try bending the plants if possible with a string attached to the top of the plant and tied the other end into a stake in the soil or in the grow box.

lower leaves always yellow and die during flowering, as the plant draws from them ... get used to tying down branches, you're stuffing a potentially 12-foot plant into a ridiculously small area ... 'putting ten pounds of shit into a two pound sack', I call it :D
