Ash, you in true soil, not Promix or coco..? If so, your pH is too low,.... it does look like Ca defc., very mild,...but other defc.'s can start out looking similar, especailly P,... no need to remove the leaves mate, and can you get me a whole plant pic in normal light please?

And soil is Fox farms Co Co loco and happy frog. A bit of ocean forest as well. Soil tested fine pre nutes is a bit low now. Run off is 6.3-6.5 though. So not sure what's going on in soil that's bringing it down more . Mammoth p maybe?

Kind hard for me to see and you know I'm a noob (please see name) but rusty spots? Maybe CalMag?

So what ya guys thinks. @Waira and @Renaissance Redneck
Do I need to up my cal mag or just a good water at 7.0 to bring my pH up a bit?
