Now that's good, solid information, thank you!
A member on another site used NLS and had similar/same issues. 12oz. NLS mixed with OF in 5 gal pots watered with distilled water. The brown spots started in veg. He had a soil analysis done. Appears that the NLS was the culprit. When I saw these issues in my grows I started adding cal/mag, high phosphorous amendments along with Recharge and Mammoth P when symptoms didn’t improve. Seeing this data I now see that I just made things worse. No more NLS soils for me unless I use it as part of a tea recipe. I wonder what the analysis looks like without the NLS?
