Anyone have an idea what is going on with these leaves? It looks like a stain but up close with super zoom, you can see almost little white dots. Can mites start on top of leaves? There’s nothing underneath the leaves
Someone diagnose this other than potassium deficiency? Never seen these weird brown spots but upon consulting Jorge Cervantes cannabis encyclopedia I’m thinking that’s what it is.. any input would be helpful.

This isn’t urgent. But two weeks ago I ordered “great white” White Mycorrhizae and added it at half recommend dosage to my 10 gallons of DWC. Next day I have praying leaves to wilting leaves and roots went from beautiful white to gunky, brown, and slimy. Anyone experience this?? 
Anyone have possible culprits for my yellowing/discoloration on Zkz 2 in pics? Zkz 2 also beginning to show small yellow spots on lower leaves. These are autoflowers, was using MaxiGro, will be switching back to my reg used Flora Trio. 
So these are starting week 8 of flower - I just started flushing these- they’re in coco. Within the last day or so they’re developing these rust colored orange areas on the edge of sugar leaves. Is this just natural during flush with coco? Or what’s going possibly goin on?
My baby died today. :sob::sob::sob:. She fell out of the window sill and ripped out of the peat. I will be starting another germinating over the next 3 days.
@Pauls5716, Aww I’m sorry .. it’s probably too late but if it just had a single tap root you may have been able to save it and try replanting.. luckily you’re only a couple days in so you won’t be delayed too bad. Still sucks!
@Pauls5716, sorry I just saw these comments, they didn’t show up in my notifications.. try commenting on one of my grows next time to make sure I see it. Anyhow I don’t use soil really anymore. I’m using Coco and DWC currently. But for a soil mix id recommend a good mix like 25% perlite, 75% soil.. or some peat moss also in there.. but I highly recommend getting some Coco even if just to add into your soil mix..
