Yea your right, as the plant matures It draws nutrients from its lower leaf and it dies off, natural. The burning of the tips of the leaf is an indicator of a little too much nutrient. The red or purple leaf stems can be a sign of stress. sometimes caused by the plant getting too cold at night.Just a little update.. not sure where I stand as far as progress.. can y'all help? Couple questions.. The lowest fan leaves up and died, no worries? Plus I've noticed some redding on the stems of the fan leaves and some tip burn on the small leaves around the buds.. should I start to flush? do you think Im near that point? It's cause of the nutes right? And honestly I've heard about using the 30x loupe to check for "ripeness", but where the's best place to look? I need to read up a little more again.. for the next stage! Still a newb... here's some pics... thanks again!!
To tell when she is ripe what you look at is that little dusty or frosty stuff. They are called trichomes. they look like tiny mushrooms. when they are clear they are producing, when they get cloudy they are ripe, harvest now and you get a good head high. if you wait longer they turn amber and will produce more of a body stone. Some say its best to wait till you see 50/50 It's really up to you, what kind of stone your lookin for. By the way if you wait till they are all amber they start loosing there potency. You see those little hairs that are white? those are pistils, they will turn amber about the same time unless exposed to a lot of light then they will amber sooner then the trichomes ripen.
What I would do is stop feeding and go with water for a week or so and check the night temps.
She may have enough nutes in her to finish as it is.
