420ben i have the same problem every cyle. i start noyicibg the brown spots 3 weeks in to 12/12. this is my 5th grow and there back right on scheduel 3rd week. i have posted and tried to find out what it is. mostly folks say its magniseim def. or rusty fungus.or to flush. i have tried many things. the good news is your buds will be ok. its seems to be astetic problem. im sure you will loose a lttle weight but i always make to the end. if i find out i will pm you and let you know. or if you find out hit me up. good luck
I am also into 3weeks of 12/12 and this is my second time it has happened to me. While vegging i noticed brown spots but not many leaves had it until i started to flower. I did flush them one time till the ph of the run off was 6.8 because before it was 5.5 and thats too low and it seemed to help after the flush but after i feed the plants it seems it come back so im thinking it could be the nutes so this time im going to wait till the soil is dry and flush them again and just use plain water. ill let you know if it works.

I don't know for sure man, but I'm at six weeks and it started just like that coming on quick, I feed them as usual, only I added just a little bit of nitrogen, and a teaspoon per gallon of cal-mag,,,It's kinnda to early to tell, but once the leaves are like that they really don't come back, I wish ya luck.

Damn bro. Well this Wednesday it will be the 4th week into flowering i am not sure if they are going to make it. I have no idea what to do. I flushed them and stopped giving them nutes thats about it. I was thinking maybe it was a nutrient lock up. Where did you get your cal-mag?

Dude, I'm having a very similar problem. I'm 3 weeks into flowering and my yellowing leaves look exactly the same with the brown spots, etc. I did what you did too and flushed but just like you said, the problem just got worse. Right now almost all the large fan leaves have fallen off and all you can see are the buds on the plant now.

Honestly, I don't think you're overfeeding because the tips aren't burnt and the leaves aren't curled. I've read that brown spots and yellowing leaves during flowering can possibly be a K deficiency. I don't want to recommend feeding anything because I'm not 100% positive but I just don't think its nute burn from what I see in the pics. Sorry I can't really help but just thought I'd let you know youre not alone with this problem and frustration. I hope you're able to fix the problem tho, good luck.

Damn man that sucks, there were a couple of other people with the same. Maybe its like the H1N1 virus but for cannabis lol. Im using fox farm nutrients by the way and i dont know anyone else that has problems using fox farm.

really you think so? maybe its asking for nutes? and sucking all the green out of it?

your definitely deficient in something. I doubt it is over feeding especially since it didn't get better after flushing. I would resume feeding with a weak solution of all micro and macro nutes (use the proper NPK ratio for what ever stage you are in right now). At this point because of flushing your plant probably has nothing that it needs.

Nice looking plants Peach. Yeah i can see what your talking about on the leaves. If only there were Cannabis Doctors that can come over your house and diagnose the problem.
