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. 
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?
I’ve done DWC several times, not a newbie. Getting pH spikes from 6.0 to just under 7.0 in 48 hrs, and an algae like dark brown/reddish substance within 48hrs as well. New stones, black buckets, 950 GPH pump feeding 1 stone per bucket. Net pots covered with cardboard. What gives? 
Wilting leaves - autoflowers wilting slowly and more intense towards end of light cycle. I assume this is normal but it’s still worrisome. This plant is a bit closer to light than all the rest, but lower buds are doing it too. Pic is 16 hours into 18 hour light cycle 
Oh that sounds great but personally for me it was a little too psychedelic I guess you’d say, or displaying those racy, paranoid, spaced out thoughts.
On top of that several times I smoked it I got a intense headache sort of. Not like a normal headache, it was like a pressure on the middle of my brain.. uncomfortable but not migraine level.
Probably just a personal thing? My body reacting unusually to it.
Anyhow nice dense buds, cheesy smelling with a bit of classic skunk and nuttiness to it.

@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..
