Brown veins on leaves and yellowing

[caesarjr]

The veins in the leaves on one of my plants are turning brown and the leaf is yellowing along the vein. I tested the PH and it is about 6.5. It is an outdoor grow, Any ideas? Thanks.

May I ask how you tested for pH? This is the 3rd post in a row I've looked at with similar problems.. It all looks like a Phos lock out..

I used a PH soil test kit by LusterLeaf. What is a phos lockout?

I did accidentally post this in another thread and could not figure out how to delete it. :-(

The PH came out at about 6.5

Your soil is drying out too fast because of the sun hitting the container. Shade the container from the sun and water with 5.5 pH water and your plant will be ok.

Thanks. I will give that a try.
