Black Leaves?

[DrHermieGreenthumb]

I was just wondering if anyone knows what is turning the leaves on my Gorilla Glue #4 black? They are 8 weeks into flowering under Spider Farmer 4000 LEDs with GH Flora Nova nutrients dosed at 1 tsp/gallon given twice weekly. Thank you for any insight.

Not sure but i had a very similar thing happen to me and i narrowed it down to the fact i was giving them to much Blackstrap Mollasses.Yours looks more like something genetic.Whats your temps,day+night.

I would go with anthocyanins here, genetic disposition, I've had this happen with plants. here's 3 that went dark: Golusa, Sugar Candy, and Forte Noire.

Temps down into the mid to low 60’s during lights off has brought out the strains colors. Perfectly normal and preferred in my tent. Looking good

Awesome! I agree with genetics.

My temps get down to 60 at night with high 70s during the day. Genetics makes sense to me with how great the plant is looking otherwise, aside from the tiny buds. I’ll update if the plant starts to show signs of struggling. Thanks everyone

It's a beautiful coloring lucky phenom you my tent with the door flap open will stay in the mid 70's lights out an zipped up will be in the low 60s. I think it is way better than very warm. It may just be slowed down a tad time wise but not as harmful as too hot. Great looking plants
