Brown spots? Rust, kalium or burnt?

YellahJellestarted grow question 2y ago

What are these spots? Growing outdoors, about 5-6 weeks old, not using any nutritients but made a mix with 1:2 Coco and soil, and some guano for them. I also found some trips, ordered neem oil for that

I had exactly this kind of spots and applied a little bit of calmag (1/4 of the recommended dosis) and it worked. Id wait for an expert opinion though :)

Yellow bottom leaves/brown spots on bottom leaves Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Calcium or other deficiency?Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.

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?
