flushed em a week ago so im sure its not nutrient lock
I think you're right, but not for this reason. You can still see problems show up after a flush.
Looks like something I had going on late into flowering. May be a magnesium problem. I used epsom salt. It wont repair your leaves but it will stop new spots. I would try it and see what happens, it wont hurt. Use one teaspoon per gallon of water.
Definitely try this. It won't hurt, and might help. Of course if you try this and something else at the same time you won't know for sure what helped, but that's a minor concern imho.
no definitely not a bug problem, my room is steralized from the start and i always use fresh clothes and no shoes to go inside.
The cleanest room can get bugs. I would double and triple check them just to be sure.
I would say it's not Manganese. Manganese is immobile, meaning that once a plant has built something using it, the plant can't remove it from that location and put it somewhere else. Like say Nitrogen, it's mobile. If you don't have enough Nitrogen the plant will steal it from the older leaver to build the new ones, so you see yellowing in the older leaves.
Since you say the tops look good, that means the malnutrition (if that's the problem) is a mobile element getting moved from the old leaves to the new ones.
pH issues also cause this kind of thing. Make absolutely sure your pH is where it should be first off. Nothing else can really be diagnosed with certainty if the pH is off.
Like I said before, we want to keep bugs on the table until a visual inspection proves they're not.
The other possibility is disease. That's the scary one in my opinion - best solution is elimination of the plant, sterilization of everything even remotely connected to it, and starting over. If you have other plants that aren't sick, segregate immediately just in case.
If the problem doesn't seem to be getting worse, I'd suggest running the epsom salts, standard feeding, and cross your fingers. If it stays like it is I'd say you've solved the problem (the spots aren't likely to go away no matter what you do).
