So My Plant is Fine but....

some leaves are falling off, which im sure its normal. and i was lookin thru the good ol scope at the hairs getting happy at the bunches of them on my plant but some of the first ones that i seen turned brownish. i know pics are worth a thousand words an all, but i just wanted to see if anyone has had the same issue. my plant is about 30inches tall. im doin some lst on the lower braches so the fan leaves dont block the light to the lower branches. stinks good too any comments on it would be nice

The hairs turning brown is completely normal - don't sweat it chief...happy growing!

Bottom leaves shouldnt really fall unless low light or low nutrients (could be somthing else though), hairs start to brown after 4 weeks or so, more white hairs will appear and more hairs will turn brown until a lot more are turning brown than white, eventually there is very little new white hairs and all the brown hairs are withered and receeded back into the swollen calyxs, now is a good time to consider harvesting at this point.

Not many plants flower all their flowers at the same time, as old ones mature and die new ones are formed, when the plant no longer has the ability to flower then it is at the end of its life or flowering cycle. This for marijuana is harvest time.

How far into flower are you? check the plant for any sign of male flowers, that and watch for the pistils to recede into the caylxes and then the caylx swelling and starting to make seeds. The brown hairs could mean they were pollinated. It could also not be that and is nothing to worry over. Leaves just falling off isnt that normal, i'll bet you they need some nitrogen. The plant uses up a ton of it during the stretch phase of flower and that can cause it to start cannabilizing leaves for it a bit later into flowering. You want your leaves to stay around making energy for the plant for as long as possible.
