Ok I knoticed on a couple leaves a dark brown spotting, not on the tips, not on the vains, no repetition from leave to leave. Its just where ever it wants to be on those couple leaves. This is the only thing wrong the rest of her is fine. Im using soil and fox farm nutes, all of them on the feeding chart. Im not able to post pics yet. But I have looked up syptoms and problems and am not noticing any resemblance. If any one has an idea with out looking I wouldnt mind a shot in the dark.
 
Without pictures it will be hard to diagnose brother. Both under feeding and overfeeding can cause lockout of certain nutrients which will cause some blemishes or brown spots. Cal/Mag deficiency can also cause brown marks but most commonly starts at the tips of the leaves. I hope this at least gives you a starting point in trying to diagnose..there are just so many things it could be without the visual :peace:
 
Ok BGrow, I'll take a shot in the dark : )
I will guess it's a ph problem locking out a nute or two.
How's your water ph going in/out?
 
I add 3 ml of cal/mag with every feeding, that is every other time. Ummmm.... I did not ph my water for about two weeks and it looked like they were not doing anything but sitting still. So I swear not to just giver her water that wasnt ph'd ever again and thats about the time she got her first brown spot that I knoticed. It hasnt really spread since the first spot just a couple leaves. I just fed her water today and am going to flush her with sledge hammer soon as shes dry. Thanks guys I wssnt sure and had no reason to be sure but thats what I was guessing. Thanks
 
a good ph pen(hanna combo or a HM digital ph-200) and a soil ph probe(accurate 8) and you will never have ph problem ever again!!! could be cal/mag as well, but without pics, those are the 2 things that would cause the spotting.
 
When I've had pH drop down in the 5s I see the spotting just like clockwork. Definitely want to pH the water and check the runoff before trying to correct the problem. More cal/mag or other nutes won't help if you're in pH lockout.
 
Yeah most definitely no more nutes. I hqve the ph tester that you drop 3 green drops in and tells you that way, any one got a color they allways use of is my ph tester out dated? I have a ph soil probe that always reads 7, I bout it from a dude who was done growing, I might just splurge and get a new one since there like 5 bucks. Thanks guys. Im going to look into a ph pen.
 
These brown spots. Lol

I'd try to get an electronic pH meter ASAP. In the meantime, what is the runoff according to your drops? As for the soil meters, the $5 are shite and will do nothing but make things worse. I stunted the hell out of my plants on my first grow because I trusted a soil meter that was stuck on 7 (aren't they all?). Good ones cost a lot, and IMO they're a luxury once you've got all the other standard gear like a good pH pen.
 
Yeah I got shafted. I bought that one an the analog one plus what was supposed to be 30 auto seeds, which turned out to be photo seeds and two junk meters. Lol but that was almost a year ago. Not sure what you mean by "run off"? I was browsing for those pens and meters, I found ph pens that are like 15 bucks and ppm meters for 15 bucks well right around there, then I find pens that ph and ppm and they are f****** outrageous. Tell me more Andy,
