I have a plant that has spots like this too, just tinier and more numerous on each leaf, but really only a few leaves have it, idk what it is either

are those brown spots appearing on upper (new) growth? or in the old leaves? are the older leaves are getting darker? stems are turning red (starting sometimes from underneath)? we need some more info and pics to diagnose correctly
it looks like it could be 3 things:
1.- pH fluctuation
2.- calcium deficiency
3.- phosphorus deficiency

hi there stealthboat, it seems like a calcium deficiency and pH fluctuation
Different strains of cannabis tend to have different nutrient problems. Some cannabis strains (or even specific plants) tend to use much higher levels of calcium than others, and so you may see calcium deficiency problems with one plant even when all the other plants which are getting the same nutrients and environment aren't showing any signs of deficiency.
have you tried to flush your medium with pH'd water with normal nutrient dose? are you keeping a close eye on pH?
in most cases you can correct that problem with a good flush
or you can include a cal-mag supplement to her feedings

I do use Cal mag, about 1 tsp per week for that plant. I thought it was an overabundance of something rather than a deficiency. Guess I'll just add a bit more Cal mag? Ph is under control now

you know better your plant, if you think it could be over-fertilizing it makes sense too, some times over-abundance of a nutrient can lock up other nutrients producing a deficiency, i would flush the medium throughly with half strength ph balanced nutrient mix and see if that restores the nutrient balance

thanks for the help guys just got back from work watered them and moved them around a bit, tomorrow ill take pics I really think the deficiency comes from not watering often it is a Calcium deficiency because of that, I see it beggining on one of my lemon skunk and its also because I let it dry a bit ....

Be carefull because thats what I think triggered my purple maroc to go hermie but it was on 60% of the leaves and I really let it dry out when it happend so it was my fault really.

Dang that's unfortunate. I only found 5 maybe 6 leaves like that, all near bottom of the plant

Nah, if I start to see the leaves beginning to droop I will water a.s.a.p., the leaves have never drooped on that plant yet.

Hmm I don't think anything is rootbound, what is the medium and nutes used again?

that on your sour diesel clones is Mould and you should treat your plants ASAP if you don't want to lose your crop friend, it will spread fast to all your garden,
in fact the plant with the deficiency is starting to show early stages of mould too.

Just to let you guys know the Hydrogen Peroxide mix with water in 2 days has almost dissapered and plants look way better, no signs of stress on the plants.
I used a 32oz bottle with tap water and added 2oz of 3% hydrogen peroxide
took them out of the room,misted the plant everywhere even the buds,
shook them a lil just to get exes off
placed back in room and gave them a 290 degree turn 4 times so the fan can drie them out.
repeated again today I think one last time and they should be all set
