Have these rust colored streaks on several leaves over the last few days. It doesn’t appear to be rust spots and I couldn’t find anything on the internet.
Any info is much appreciated.
Thanks, Bonjoyle! I just saw this response you left. I didn’t get a message that anyone had replied, so apologies for getting back to sooner.

Looks like phosphorus deficiency starting, pics of whole plant and media type, lighting, room conditions all would help to diagnose correctly. Are you giving them cal mag? Also you need to inspect them for pests, when I blow pics up, it looks like spider mite bite marks. You will need a microscope to see them, look under leaves near the veins, if you see webbing or little monsters crawling around, it’s spider mites.
Thanks Growdoc. I cut her yesterday. She is/was a sativa CBD, so I didn’t know what to expect.
Her stems were solid and looked healthy, but her buds were small. No sign of webs or mites, just those brown streaks between the veins. That’s why I thought it may be some kind of disease.
We are in south-central Texas, and I grow outside, in pots. The climate is warm to hot with low humidity and plenty of breeze. I always use fresh Ocean Forest and water every 3-5 days. Every other watering I feed with Fox Farms Grow Big which contains mag and . Since I water with hard water. I haven’t worried too much about cal. I always let the water set for the 3-5 days between watering so the chlorine can dissipate. I use Captain Jack’s Dead Bug and Neem Oil.
My pH tends to run high, 6.7-6.8 from the hard water. My next grows will add some garden sulfur to bring pH closer to 6.5.
I’ve only been growing for a few years so I’m still fine tuning my process.
I had not thought of phosphate but will add it to the mix for the next grow. Many thanks for the guidance.
