Did you change anything in week 6? pH, bloom booster, cal-mag, other additives, temps? What medium?

Interveinal chlorosis(yellowing between the veins) followed by nectrotic spotting(spots of dead or dying leaf tissue) , then necrosis (full-on crispy/dead leaf tissue), is what I am seeing. It should have progressed in that order. Is my assumption correct?

They definitely still look dank bro... I think you have either nutrient burn or have you sprayed and/or burned sulfur recently? Sulfur reacts with certain sprays and can REALLY fry them if your not careful.

It's going to be dank either way. You can start flushing with phed water either until they are done or if they look worse start feeding again at lower doses.

What's up man, yeah definitely progressed.. In soil with biobizz nutrients.. no cal mag but I never need extra calmag hpk as booster temps in mid 70's.

What do you think it is? Consensus is nute burn

I would lean towards this as well. My logic is that the leaves are necrotic and showing chlorosis in inconsistent areas. The tips of almost all the leaves however are burnt, which to me is indicative of nute burn. I've noticed that the cookies, while in some ways hardy, is also sensitive to light and nutes. It doesn't really seem to need much to produce. It's fickle in it's own ways.

Glad to see you running it man. I'm sure you'll have it dialed in soon, and those nugs will be proper...Keep it up as always!

"Burned" leaf tips don't always mean nute burn. If it was just the tips slightly burned and you had necrotic patches on your bigger fan leaves, I'd say it was a calcium deficiency. But dialed soil and good water rarely lead to Ca deficiencies. I've also noticed the GSC doesn't need much extra CalMag, unlike many pure OGs. She really isn't a fan of Nitrogen, or heavy feeds in general. I'm just running her now for the first time, so I'm seeing all of her tendencies.

When I see bottom of mid leaves curling upward, I assume a Potassium deficiency. Too late to try to fix it now. Next run of her, I would suggest upping your Kelp Meal in your soil by 40-50%, and go lighter on the nitrogen.

Sweet. Thanks for the explanation. Thanks to all who have replied. I really don't think it's affected the buds much at all, they look on point imho.. This is a pretty strain no doubt.

Spacecase.. So your saying its not burn? I'm honestly confused. I did just add seagreen to the regimen but only used it at 1.5 ml / gallon through week 5.. Does too much nitrogen reduce the availability of potassium? Does cold soil temps decrease the availability of potassium? Those are the only variables that have changed. And by cold soil temp I mean the ambient air is ~71 at pot height compared to ~79 in the summer at pot height. That picture was taken a little less than two weeks ago so she's about ready for the chop. More curious for the next round.


Edit: I don't ammend my soil I use straight Roots. I use algemic or maxicrop extensively so they get plenty of kelp.

I concur. Well said.

@self.- Yes in regards to your question about N and K. Between N & K exists an cationic/anionic relationship. Potassium is generally 1-1/2 to 3 times higher than Nitrogen for vegetables, less for flowers.
As well, colder temperatures do not decrease availability of K. Due to decreased evapotranspiration higher EC is common practice durings cold periods in greenhouse cultivation and open field crops.
