This is starting to develop all over my plant this week:
This is a Durban Poison being grown in 5 gal Fox Farms soil. The only neuts are Osmocote Plus mixed into the soil. This plant is in week 6 of flower.
When this started about 5 or 6 days ago it looked like fine yellow pollen dust collected in the veins of the leaves and because this plant is a hermi, that's what I thought it was. But it has gotten worse and worse and is obviously not pollen the leaves are suffering.
Many leaves all over the plant are affected. I guess it is mostly happening on the leaves that have the most light exposure. This leaf was from pretty high up on a main cola branch.
I've been looking at all the neut deficiency charts and while it does look like I'm strong on N (because the leaves are very dark green) I do not see any symptoms where yellow spotting starts to spread from the veins. The only thing I could find was ozone damage which presents itself in the veins like this.
Ozone sounded crazy but I looked up sources of ozone and it said paint thinners and oil paints can be a source of ozone. Those items are in house, but far from the grow room. I can't be sure if that is really the problem but I moved all that stuff outside to be on the safe side.
Does anyone have any experience with this symptom?
