Is This a Potassium Def or PH Problem?

I have an electric PH meter I use before I add any nutes. I am religious about PH'ing between 5.8-6.5. It could be the soil?
 
test your run off water the soil should buffer it.if your soil is at 4.5 like mine u need to give it about a ph of roughly 7.p ur runoff should be around 6.5.don't flood the medium either give it a little bit of water at a time an let the soil soak it up the water.as the water runs through the soil the ph buffers go to work.

I am using FF Ocean Forest with about 30% Perlite mixed in.

As far as nutes go, I've been using GH FloraGro, Flora Bloom lately as well as GH CaMg+ and Snow Storm Ultra. I just recently purchased Bud Candy by Adv Nutrients. I had been using GH BioWeed as well but as of lately. Oh I had some GroBig in there as well. Maybe just too much nute altogether now that I jus read over what I've been giving them....

5.8 - 6.5 PH for a soil grow???? Thats more like a hydro grow

Soil grow should be 6.3 - 7.0 ..

You probably are locking out some nutrients because you are using a PH thats suitable for hydro grows

I had a few of these on one of my mother plants recently also. I cut them from the plant and did not remedy it in any way (change nutes, PH, or anything) and I have not seen it since.

That is TMV. Don't worry a lot of plants have it. Nothing you do will fix it and you can't get rid of it. Up your Cal-Mag and they will supress it. TMV is like herpes for marijuana.

Its getting a little worse over time. I had no idea that my PH should be so high. Should I over correct for a couple waterings? Either way I will correct immediately with my next water to be closer to 7 and add a little more calmag. Thanks for the help!
