Dry Brown tips/edges with upward curling

[Hypathetical Gardener]

As one can see, late flower. Og kush. Its done in 2 weeks. I noticed this starting a while ago (attributed to heat) but it is persiating and seemingly spreading. It was on a few leaves on 1 branch. Now its all over.

Think on it:
Does knowledge have intrinsic value or does it need to have a practical use to have value?

She still has a long way to go.What are your temps? How close are your lights?

Sorry i fail. I know better.
I think shes 2-3 weeks ish from my ideal. But shes getting chopped in the near future as i need her place in the tent.
Lights on is 74 to 82
Lights are 12 to 18" away(315 .cmh)

..light is too close, 18" minimum,... I can't see very well in those pics what you're concerned about, is it the brwoning along the edges? ....might be early K defc., that could be in part due to the lights causing troubles relating to transpiration,... I see unusually poor bud:leaf ratio too, so review your nutes, dosage and schedule for us please,....

I am referencing the burned edges and slight tip curl upward. I was concerned i was overdoing something somehow.

I am using a slightly modified roots organic feed schedule for dry amendments in recycled and reamended ffof×cocoloko. I topdress weekly. The last 2 weeks ive watered with light molasses about 2x a week.

Ill move the og down a bit. I have it raised because i raised the light and the ak/domina were shadowing it. Ill give it another few inches or so.

Heres the schedule. Im on bloom 6 and its actually been really accuate as to when it transitioned so that was nice.

....necrosis is a common symptoms of most defc.'s, not just nute burn,... where it happens is a big clue too,.... So if this is all she's getting, then I think the K supply is weak, and it's starting to show now,.... K is really important all the time, which is why you may see it's number pretty high regardless of N-P ratio (in synthetic nutes),.. K is harder to get in "organics" per se, bat/bird poops usually aren't that rich in it,... Roots does have HPK as a supplement, or you can just use a little regular bloom nute's to get right-now available K in there,...

bro, K is critical for terpenes, so at least look into a supplement, even wood ash... "Organic" doesn't really apply here for this, and a little synthetic isn't going to foul anything up at all,.. I usually run a mix of both,.... hell, I even have used salt substitute (KCl) for slipping a little solo K in there, and Cl is actually a needed micronutrient,....

Im eventually going to move into that "artisan" style of organic mixed with salts. I have recently topdressed some bloom mix 254 and added some bio so it should hopefully clear up in a few days. Thanks !!
