Need help identifying the deficiency here
I just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!

Leaf issues. Lockout? Need to Flush??
Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??
Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloom

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

They look the same, so is there other criteria to differentiate a calcium from a manganese (not magnesium) deficiency?

Calmag every watering?
Should I be adding calmag+ to every watering? I've been using 50/50 pur+ tap water and distilled water. Ppm is 245 at 50/50 and pur+ filters chlorine. I've also added 1tbsp per gallon of unsulphured molasses and that adds 68ppm. Day 40 right now.
