My cookies are black

[Pumert]

All my other clones are thriving in this soil mix, but my girl scout cookies are developing black fan leaves. The only noticeable difference between my GSC clone and the others would be how i was unaware how weak the main stalk was and for the last few weeks i have had it propped up with a skewer and some twine, could the metal from the tip of the shish kebab skewer be causing these black fan leaves?

She started to more in flowering. Usually the dark comes from cooler temps. I don't think its a problem. But I'm no expert. Get a better pic up and hit me up.

You feeding her kool aid?

 

[HGK420]

all seriousness she might want some P. check this place out scroll down to the phosphorus deficiency. http://howtogrowmarijuana.com/nutrient-deficiency

Strains with purpling purple instead of yellow in some cases. Just substitute the purple striping in your mind for yellowing. It could be potassium deficient. Could also be P too, but it's just rare that pot growers get P deficiency... they usually use too much. Weak stalk also leads me to think K.

If not the cold, I'd say a phosphorus def, which is pretty but will reduce your yield.

Good luck

you make very well points i just wanted to mention that the stalk was already weak to begin with, i think some of the bark ripped of when the clone was cut because theres a brown mark on the base i didnt notice until afte ri bought the clone, no refunds...

LOL I thought you were talking about burning edible cookies.

Imo serious P def presents otherwise, with plainly hurt leaf vitality. My 2¢ are on cold andor plant characteristic. cn
