Reoccurring problem

[Jupiter]

So every once in a while I get what appears to be I guess a phosphorus or potassium deficiency. Need help.
This plan is around 30 days old in the soil pH is about 6.6 done with the ph/moisture probe.

I'm no Dr. but this looks like Nute burn. I say that only because of how sporadic it is. Also, your plants look a bit heat stressed. That leaf curl is usually a direct indication. Could also be too much air from the fan blowing on them or too low RH. Can you provide more information on your grow for us, please? Temps, RH, Nutes, PH of soil / runoff?

So my soil pH of 6.5 done with a soil/moisture meter. My Ec is usually between 1/1.4. My humidity has been around 50 to 58 and as far as air movement I have a few oscillating fan on low . I run roots organic but nutrient burn seems to fit the bill. They did get a little dry about a week ago.

On my current grow they went a bit too long with out water, and dried out. They had similar symptoms you're seeing. The bad leaves won't come back. But, a feed or two with play water, and maybe a little cal-mag might be a good starting point. But, again, I'm no Dr. I'm diagnosing with very little experience. I recommend you see what @Waira or someone with that kind of experience would say before you do anything.

Yeah appreciate the input though. Also found my ppm meter had to be recalibrated. Oh well

...yup, likely nute burn from cumulative build-up,... get an better soil pH probe too, like an Accurate 8, those skinny probe combo meters I've put to the test and found them unreliable for accuracy... Calibration on pH meters and EC/TDS meters is needed fairly often, depending on usage time,... EC/TDS can certainly go longer than pH meters though! If it worsens it might be wise to flush the soil, and be sure to include a 1/4 strength dose of nutes on the final pour,...

Thanks bud. On top of that I found some thrips on my leaves. Will the go away in colder climates? I have some nematodes coming for the soil but nothing for the leaves.

gaahh! I hate those little turds! Cool weather may slow then down, but I'd spray them with a safe pesticide over a week to kill off all generations... spinosad containing products are my favorite, but there are several good choices, just depends on what you can get,...

Top cover the soil with dry diatomaceous earth bro to shred those bug
