Cal/Mag Def?

[Magic]

Hello guys, all my plants are doing this at the bottom lower leaves and i noticed that my polor express whats looking to have brown spots on a few leaves, i know this isnt "plant chicken pox" wondering what it was? My soil ph meter will be here today, and my soil ph canculated by run off is 5.8,6.1 and 6.4.

I have this on lower leaves of my plant too. It looks like it's hungry for nitrogen, that's just my opinion. Maybe others can chip in on this and help you more

Other than Nitrogen def i'm thinking heat stress, nute burns or ph lock out ?

Post up some pictures of the whole plant so we can see the other leaves as well. If it's just those very bottom ones, it's quite common for those to die off on more mature plants. The browning along the edges and the larger brown spots indicate a P, or P and K deficiencies, not cal/mag. But I'll reserve final judgement till we can see how the rest of the plant looks.

Nice looking plants. Sure you will get this sorted

I wouldn't be concerned, the rest of the plants look fine. As I said, it's not unusual for those lower leaves to die off once the plants get a lot bigger. They are being well shaded by the rest of the plant so are receiving little light. Once your soil probe arrives take some readings and get the true pH of your soil. I assume you are getting an Accurate 8? If so, take 3 readings on each pot and average them. Make sure to clean the probe between each reading.
