Black growth??

[waldoeGeek]

Hey, been having some black growth. Outdoor grow in soil. Started feeding couple of weeks ago, ph is fine. Started noticing the new growth is black-ish. Was thinking phosphorus maybe? But feeding it doesn't have any affect as new growth continues to be this color. Pretty sure it's not genetics as I grew this strain last year and didn't look like that.

it might just be that pheno. Does the color correct once it grows out some?

Sort of. The color goes green except on the very edge of the leaves.

only time I see that color is when I'm at the end of a grow and my sugar leaves turn.

I've had sugar leaves turn that purple-ish near harvest as well, this one just started flowering. This plant was my mother, It's been growing since February. I took 2 rounds of clones then stuck it outside to veg. The clones also have this color happening.

Has it gotten colder than normal where you are?

I ment at night. Sorry, I should have clarified. Night time temperature drops of more than ten or fifteen degrees can cause that. So can being a little low on phosphorus and magnesium. But if its not hurting anything I wouldn't worry. I had a Gorilla Glue x Mendocino Purp do that this time last year and it came out great!

You have purple top phytoplasma disease, it's spreading like crazy in the midwest because of potato farmers. Leaves will start to curl and look sick soon, your best to cut off any infected tops before it gets worse.
