Browning cola ends

Hey guys,
So after a whole summer's work and care, I began flushing the plants of ferts last week. They were looking fine until recently. It seems like top of the colas turned a very nasty-looking brown and touching them they were very dry and "crispy". I decided to chop yesterday anyway and just cut the tops off (yea, there were a few tears while doing that). Since this was my first grow, and it turned out pretty well for the most part (got nice looking bud, and more than enough for my personal use which was my goal), I didn't mind losing out on the pieces I disposed of.
Anyway, for my next grow I want to make sure I avoid this problem. So what could have caused this? Is it because I went straight from regular dose of nutes to none at all? I know I kept them watered enough, and they were definitely not too close to the light. Thoughts?
I'd post pics, but I'm out of batteries, doh.
Thanks!

Get some pics when you can... Hard to say. Did you let the plant go too long? I have seen that before. Or maybe budworms... But you would have most likely seen signs of them when you chopped her down.

What were your temperatures like?

I'll get some pics posted up tomorrow, didn't get a chance to buy some batteries tonight. So that might make it easier on you guys to determine the prob. I don't think I left them go too long, really I may have chopped them a little early (due to the browning situation, kind of panicked). Pretty much certain it isn't pest-related either, the plants were isolated and sprayed with neem oil throughout veg, and I was extremely careful when checking them.

To be honest, they were fine until the last few days before I chopped. There was a severe heat warning or whatever here, so the temps may have risen a bit. Could that have caused it? Just random how the top buds turned brown and crispy, but everything else was nice, green and moist.

it could raised the temp of the room enough that the lights burnt the top with a bit more heat
