Not to hijack your topic but it'd be awesome if someone could clarify this, now I'm scurred

What strain is this? I have OGs and they tend to have redish purple stems but its part of the genetics I heard.

I Started from a clone labeled The Goo so im guessing Afgoo. but im not too worried about the red it is the brown necrotic spots that worry me the last couple days they seem to get worse could it be because of the Jacks classic i fed her, it seems like every time i feed something happened to her leaves. i flushed her out the last time because i saw some yellowing with tiny brown spots. now the spots are ten times the size as seen in the photo.

Some strains do have red stems, some but not most. I have had red stems in the past and it was from stress. I noticed when I switched to a 10-10-5 nute the stems quickly lost some of the red. But I also stressed the hell out of them by stretching them. They never seemed to kick back 100% but they were still fine. Sounds like the same situation I was in. Imo get on your nutes and take a breath nothing happens overnight lol. You should be fine they don't look past the point of no return by any means.

So today the spots are even worse and the leaves are turned upward now. i will post more pics, i dont know if i need more nutes of to flush

Ozone Damage:

Ozone damage typically found near the generator. Although a rare problem, symptoms generally appear as a Mg deficiency, but the symptoms are localized to immediately around the generator.

Here are some pictures taken today i dont know what to do and fear she might die and quickly from what ever is wrong.

Yeah i dont think that is my problem but thank you for your input i really appreciate it.

Phosphorous deficiency. Without a doubt. It also causes red/purple stems. Sound familiar?
The hard part is whether it's from underfeeding or lock out. Looking at your first post, I would say she's hungry. Most organic soils, like Foxfarm, feed up to about 2-3 weeks into flower. You need some nutes. A simple bloom booster like you have isn't going to do enough, it's only a booster after all. I would recommend Gen Hydro 3 part at about 70% of the recommended dose. Simple and cheap. Get it today, phosphorous def moves quickly and WILL kill the plant in a week or so.
