Question about leaves drying and pointing up near end of flowering

Hello guys...
I am pretty close to harvesting one of my seven. She is a Northern Lights Blue and she started showing sex at day 24 of veg. We are on day 41 of flowering and everything looks good except for her leaves. She has had small 7 finger leafs throughout. Today I noticed the tips are pointing up as are the sides, almost taco like. They are getting dry even the lower leaves. I'm hoping this is a late flowering sign and nothing bad. She was watered yesterday so it's not dry. She is about 12" below a 1000w HPS lamp but that's normal for all the girls. Trichomes are mostly milky but no amber noted yet. Any opinions on what may be causing the leaves to crisp? The current closet conditions are 77 degrees with R/H ~38%
Thanks for any help.
Any opinions on harvest time is appreciated as this is my first ever grow....

Sorry about the yellow pictures the HPS lamp makes for shit pictures...the first two are pictures of her in good light after taking a small sample a few days ago...

Lowered the plant about 6" from the lamp in hopes it will fix any heat issues....

Don't know about a 1000 but my 600 bare bulb stays at 18" away from the canopy. When i ran a 400 I could run about 10" from the canopy.

I keep a daily journal and see I started off as far away as 24" but slowly lowered to where I am now. I'd say they averaged 18" above the canopy but it's still only about 80 degrees 6" from the air cooled hood. I have been able to place the back of my hand a couple inches below without close to burning. I would use 18" as my target. Right now the 7 ladies sit about 12-16" below the canopy.
Looking even closer I noticed 90% cloudy trichomes and most hairs have receded into the crystallized bud. There aren't many leaves on this plant but the one's she has are fairly dry but the buds look puffy and happy.
To chop or not to chop?

Look to the chart for the correct distance, have you flushed your plants lately ....? to my blog:

If you really want answers . We need more info and a pic with the hps off.

I will have more info and pics within the hour...thanks

Vostok...thanks for the chart. Seems I'm good up to 12" even though they have been no closer than 12 they have averaged 18"

I have not flushed them and I plan on doing that tomorrow or next day.

Pics very soon, are there any things I should note so when I reprt back I have the info you experienced growers need...

Pictures are difficult as the closet light is above the lamp which shields the plants and makes shitty pictures. This was the best I could do. This set is natural light and as bright as I could get it.
The leaves have a upward claw look to them and they are dry on the tip and edges. I have them in Fox Farm Ocean Forest Soil and they had their last nutrient feeding yesterday. This is the first sign of any distress but I thought it might just be a late flowering sign. The buds hairs have receded but I don't see amber trichomes, mostly cloudy/milky and a few clear. She started flowering very early, about week 25 of veg and after 35 veg days she's on day 42 of 12/12.
The other 6 white widows have no signs of distress at all.
Hope the info and pictures help, please let me know what else I can answer for you....
Thanks

Pistils are all brown. Frosty and ripe looking to me. Nice looking buds. Plus rep

They are over fed. The first sign of over feeding is the tips burn like that. And it looks like the salt content from the nutrients are starting to slow water uptake and burning the tissue in the leaves. So you have a mild case of nutrient burn. With how fed they look I would not feed and let them eat what they have already. Best thing would be to flush them with 3 gallon water for every 1 gallon of medium. With how dark those leaves are and how much time you have left you may still have a hard time getting them to finish eating all the nutrients they have stored in there tissue. Hope this helps, if you kept a log try feeding at half the rate next time around and I bet you get even better results white widow can take some heavy feeding too, she is a strong plant!!

As far as light distance is concerned, you can keep lowering them till you get light bleaching if you want. It's best not too but I have had plants grow up into the glass of a vented hood and a 1000 watt light and all I got was some light bleaching and a little burning from the hood being hot even though I have a 590 com fan running cool air through my hoods. I may need to upgrade my fan to a 1200cfm but that will come at a later date happy growing!!

Thanks Got4m2e0
I have kept a log for everything I do and I can tell you the girls are fed every 3rd day. They started out on 1/4 nutrients (FF Grow Big, Big Bloom) and slowly got to full strength feedings with only distilled water every other feeding. They were fed only water 6 days ago and 2 tbsp each of Big Bloom and Tiger Bloom. So they are due for a distilled watering tomorrow (none of the other 6 girls show any distress at all). The other 6 have a couple weeks left and are now on distilled water only.

I have never flushed but will do so tomorrow to the girl ready to harvest. She's in a 4 gallon pot so I will flush about 10 gallons????
After flushing her tomorrow when would you chop??? Could I flush today if she's not due to water until tomorrow??

What time of day would you chop, before or after light cycle???

I plan on hanging this girl in another closet where the temps and humidity are ~74 degrees with R/H ~40%. Current R/H in the house is 8% but it's 40% in the grow closet...fucking hard winter here in the northeast.

I'm in the northeast too and yeah with the polar vortex (which really wasn't that bad) it can get rather dry in side. You want to maintain a humidity of between 40% to 50% RH for anywhere from 7 to 10 days. Make sure to keep a small stem and if it snaps they they are ready for curing. Dry them slowly otherwise they will smell like hay. Not a pleasant outcome.

Flush and wait a week to two weeks. That is the optimum amount of time. The dark green leaves they you have is how I could tell they got a little too much food. Each strain is different and within each strain, you will find that each pheno is also different. Some being more tolerant to heavy feeds than others. The only exception would be clones. But then again a well rooted clone will be able to take a bit more food and abuse then a poorly rooted clone.

I know you didn't want to hear the two week part. But trust me, you will be much more happy with plants that are in a in longer and are lime green with some nice fall colors that have been in for a few extra weeks than dark green over fed plants. Don't get me wrong they look like fantastic buds for someone with limited experience and I think you should be proud of your results either way. But I would give them a flush and a few more weeks and they should be able to eat up the extra nutrients and start to get a little bit of yellowing fall color going on. Besides nitrogen at high levels delays maturation of buds so more time can't hurt. Also I ran strain for 6 -7 weeks longer than they had to and the only result was more density and a nice coma after cleaning out the fridge. So you should be fine. Good look, great job and as always, happy growing

Ohh yeah, and the cooler the better when drying. At least keep it around 60 and you will help preserve the terpenes and have some extra stinky buds when they are dried and cured. So stinky that even in a sealed mason jar, the smell will permeate the room. I am not making this up, my computer bag had a jar filled in it and my wife could smell it in my computer bag hours after the jar was taken out of it I like my qrazy train strain. I got the balanced pheno will equal parts from the mom and dad that is killer stuff. Even people who don't care much for smoking tend to love it so much they want to smoke it all the time. I run her 70 days and get a great mix of body and mind and a great sense of happiness. Have fun and as I always say, happy. Growing!!

ohh and I chop shortly after my lights come on, as long as the soil is a bit dry since it will cut down on drying times a bit.

Thanks for the advice, I'm going to take it! Flushing her today and watching for some dilution of her dark green...then, off with her head!

  I know I am late to the party...
  Quick-- The area between the lights and the top of the cola, this area, gets 4-8 degrees hotter, and 4-8 RH points lower....
  
  I think the only issue you have is this, low humidity at the top cola...
  Measure your heat/RH there for laughs... Bet it's real dry, and much hotter than you realize...
  
  Flushing is a waste of time, your plants look fine except for this low humidity issue...
  
  You might be barking up the wrong tree...

I have found, Leaves curling up taco type, is a Heat/Humidity issue...

Flush if you like, however, a week later [from now] what will the flush do?

What you do to your plant today, will show up in a week...

Flushing, then a harvest... the next minute/hour... is just a waste of time...

What do you think happens magically to your plant minutes after you flush ?

Nothing, especially if then you harvest...

How can a quick flush, then a harvest right after do anything, to your taste, health, up take, anything to your plant.... Think Logic....

Thanks Sand...
This is what I discovered just now. Today is watering day and the other 6 girls are bone dry as usual (I water with distilled every 3rd day and only fed nutes every other watering) But the plant in question's soil is still pretty damp. She looks great, leaves appear to have stabilized since lowering a few inches.
Any idea why she would still be wet? This is the first time this has happened to her. Everyone else (The White Widows) is dry.

Thanks also for the kind words on how my plants look. I'm really trying!!!

Besides the obvious... I have found, my plants up take the last 7-10 days is less... Maybe that's it... start of less up take...
Good Luck man!
