Leaf Issue!

See Attached Photos.
This has been an on-going issue for quite some time now.. PLEASE help me out fellow growers-

Using:
-Coco
-Smart Pots, and water about every-other day to every three days per plant
-Advanced Nutes (When Applicable: AB, Bud Igniter, Voodoo Juice, Sensizym, Big Bud Coco, Bud Candy, Overdrive, and Sensi Cal Mag Xtra)
- I distill (R/O) my own water and house it in a 37gal barrel, with bubblier
-Kind LED 750's inside climate controlled (75*-80*f) tent

I measure out nutes to what the respected labels suggest, usually 8ml/Gal... Temps are cool with minimum humility. PPM's average 1300... ph is 6 to 6.2 (I never adjust it, due to Advance having "auto PH") (I do adjust in flush)

Thoughts?
I'm grateful in advance!

Looks like nute burn but I don't know anything about those nutes.

Possibly even light burn.

How old? Looks like she's just ready to chop...

I always go a little lighter on the nutes than what the manufacturer states, each strain handles them differently.
She does look ready to chop

Crispy can be from leaves on a plant ready to chop. your plant/s look ready to chop to me. Are you having leaf problems in the rest of your grow? Like veg etc... Your ph seems high to have success with coco. So I am curious. 5.7-5.9 is my usual range to not have any deficiency issues. I Have been doing coco for awhile now and PH 5.7-5.9 and using CalMag are imperative to success.

I agree worth the lower ph, but with advanced ph prefect technology, I've heard not to adjust. Has anyone heard something similar?

Ready to chop? ? Even with those white stigmas showing? Looks like maybe she might need a week or so more to let them suck in and change color. Thoughts? Ideally you'd want to check the tri's colors though, if you've got a jewelers loop or something similar. ....

That's plain old fashioned phosphorus burn. You're gonna taste that., maybe not much it will lose some sweet taste.

noway dudes...its cannibalizing itself...nothing you can do at this point, your plant is dying

The tips of the fan leaves start to turn brown around week three of bloom. During Veg, they are perfect.. And the leaves I posted were from different plants, at different stages.. Perhaps I should dial-down the nutes, from 8ml/gal to say 5ml/gal?

I hear ya... Everything I've ever read is 5.8 ph is ideal for coco... However, The Advanced line I use, designed for coco, keeps it higher... and says not to adjust. Should I reject what they say about adjusting it?

The flowers themselves are always relatively perfect... They have weight, taste good after flushing, and burns fine... It's appears to be simply affecting the leafs, which in turn I'm sure IS impacting the overall potential of the girls...

Man! I agree about the possible light burn... It seems the outsides stay healthier, longer, than the inside leafs...However, the LED's are at least 2 feet away at most parts of the canopy...

Looks like you've overdosed your plants...I run AN with most of there additives and I've found that when I go above 1100ppm I start to see nutrient burn.

Man! I think you're right. I've been going off the recommendations on the AN label as to how much nutes to feed. For example, 8ml/L for AB.. 2ml/L for the additional nutes like bud candy and bud ignitor. Every watering. Every other day. I'm assuming that's my problem. As of a week ago (three waterings) I've dialed back the amount of nutes to about 5ml per gallon for AB, and 2ml per gallon for the other nutes, and they all seem much happier... I hope it's fixed!
Thoughts?

Sounds good, don't have too many suggestions scene you're growing in Coco {which I've never used} and I am growing in ProMix.
