flowering stage problem

my plant has been flowering for about 45 days now, but I've noticed that it doesn't look healthy anymore. Some of the leaves started to turn brown and looks burnt, and as you can see in the picture some steam ends of the leaves are cracking open and looks as if its going to fall off. I'm not sure if it's a disease or it's normal because it's almost time to harvest, or could it be bugs because I've seen a lot of black bugs, white small caterpillar looking bugs, and other bugs on the plant. Can someone diagnose this problem. thanks.

lol well if you see bugs on the plant man that may not be so good.. clear the bugs out and then see how much of a difference you gain.. you shouldnt just let bugs crawl on your bud bro.. thats marijuana abuse!!

oh yeah i do kill them and their eggs. but they are too small to see sometimes and they like to hide inside the bud and lay eggs. i try to take out the eggs but some are too hidden and i don't want to harm the bud and remove trichomes.

Looks like just the normal par for the course near-flowering harvest. Lower nodes will shed their leaves (usually) and if you see bugs, go buy some pyrethrin spray, it's safe to use until about a week before harvest (They say up to day of harvest, but we don't wash our bud off like we do our tomatoes and stuff, so you've gotta give the chemicals a week or so to evaporate off the buds and such.)

Everything looks fine and on track. Don't fret.

Looks like mine so your good and so am i hell yeah great grow!!

i hope it's just a signal that it's almost time to harvest. the bugs aren't doing much on the weed. they are just chillin on my buds. this plant is organic kush and i don't really want to use chemicals on it. I guess i just deal with the bugs but thanks for the information.
