I’m trying to determine what’s causing this odd looking coloration on this leaf…I don’t think it’s powdery mildew…just don’t know.
I have one plant in a grow tent. It’s been chugging along nicely till I saw about 5-6 leaves like that…
Im about 6-7 days from chop…
Thanks for any help…

Kinda looks like advanced stage calcium deficiency but this close to your planned chop id let it ride imo. But I’d trust og’s opinion over mine, he’s one of the many talented growers here.

I wouldnt even be concerned with a healthy plant like that this close to chop. Looks like calcium to me also tho.

Ok…I won’t sweat it.
Thanks for the reply!!!
Ok…after further investigation I think this is spider mites…
I see some microscopic black dots moving around on the underside of some of the leaves.
Now I’m not sure what to do this close to harvest. Any suggestions?
Thanks…
My thoughts too.
Once you’ve had em ya never forget em. 
A 50/50 water/ peroxide mix should knock them down long enough for you to get thru this harvest. Spray at lights out
For future grows , Capt jacks dead bug is ok up till day before harvest and then do a bud wash day of.

In addition to the peroxide treatment and the suggested use of capt jacks dead bug, you could also sprinkle some D.E. On the top of the soil to help eradicate them.
I’m not sure how effective D.E. Is on spider mites, since they hang out on leaves….and it might just be overkill if you’re also using the captain jacks dead bug, but those things are relentless and can ruin your plant quickly if you don’t get it under control.
You are so far along, hopefully any damage they do will be limited, but I’d throw all the big guns out, and definitely do a good bud wash after chop so you are less likely to be smoking little critters
(DONT USE NEEM OIL as it’s no good for a plant that’s in flower)
I understand. I’m sorta still flippin out being so close to chop…not really knowing what I can do being this far along. I really don’t wanna do any spraying at this point…neem is out…capt jacks sounds like a preventative too and I’m too far along there too…
Never done a peroxide douse…hell, never had to do anything at this stage before…
After an exhaustive search this stuff…GrowSafe…appeared…
Anyone have any experience with it…or have an opinion on it’s use?
