Top Bud Drying Out Before Harvest...w/ PICS

So I am just about ready for my first harvest, 3 bagseed girls 70 days into flowering today--400w hps in Ocean Forest w/ FF Nutes. Temp is around ~84 during the day and a few degrees cooler at night. RH is ~40% during day, 55-68% with the lights off (I use a portable a/c during the light cycle and a 12" fan for the night to reduce risk of bud rot).

I take the plants out every morning (8pm) and give them a general inspection and check the trichs using a 30x radioshack scope. In the last couple days, I've noticed the top buds on a couple of my plants are starting to feel a little more dry than usual. They have been flushed for almost 2 weeks now, and get watered every 2-3 days. The two plants feeling the most dry are the one's sitting ~7-9" from my 400w hps (actually, it's a 360w Eye Sunlux Ultra Ace HPS conversion bulb that runs in my 400w MH system...puts off 45,000 lumens).

Is it bad if the buds dry out a little before they are taken down? The trichs are mostly cloudy-headed, though some are still clear, and some are clear but have a distinct amber tint to them. I have seen probably 5-7 completely amber headed trichs between 3 plants, over a 4-5 day period of checking.

Here's a couple pictures now that I've given a little background. The fan leaves and even some bud leaves had a bit of a deficiency about 3 weeks ago (possibly a lockout issue due to one watering with a slightly-basic water) but the buds never seemed affected and continued growing just fine.

The first three are of the tallest plant, ~31" with good lean on her...


Here's a closer shot of the top. It looks fine, though I think the smell has begun to change a little in the last 24 hours. When I touch the top, it doesn't feel as wet as it did a few days ago.


Here's a couple middle buds. Pardon the cat hair...


Here's the other plant getting a little dry. She's ~28" and much different genetically from the tall one.


Top looks nice though, but also getting a little crispy to the touch. No visible sign of this however...only tactile, which makes it hard to share I suppose...


Another top shot.

So, I think they are looking pretty good, but I'm still waiting on those amber trichs. I've been considering chopping parts of the plant tonight and letting the rest go for a couple days, so if I had to chop the tops I wouldn't be crushed. But if they are in fact drying out while still on the stem I will take the tops for sure.

Thanks for reading all that...comments are welcome and appreciated!

Eww cat hair on the precious buds! i hate cats
