My Ph is 7, this plant is the same strain as 2 others I have and it gets the same mild nutes that the others get so Im not sure what this is. Its taking over my plant and I need to fix it quick. Any ideas? Theres alot more yellowing than this pic shows but about a dozen leaves are affected.

I appreciate the reply with the chart thank u. So if my soil is slightly out of range how do I adjust it? Has anyone else had this problem if so how did u fix it?

Flush with desired PH water until the run-off matches, I believe.

That's right above. Just make sure ur checking ur correct ph when flushing and test your run off till your happy normally double your pot size so if ur in a 2 gallon pot then flush with 4 gallons but not sure how you will do this with a outdoor grow ? Straight into the ground
