What defect is this!? Please Help.

Okay soo... My Big Bhudda Cheese, last 2 yields went extremely well. Very healthy, a few defective leaves(Phosphate) but for the most part is was a great go. Now all of the sudden my plants are getting these horrid necrotic looking leaves all over. Pure brown on the fan leaves. I am running the same nutes I had been with my last 2, the temp/humidity isn't as far off, bubbleponics system with a perfect ph... I just don't know what the problem is. Any help is appreciated! I'll post some pics. One of last 2 yields but, then the defect.



That's what the buds looked like, the pic on the right is the defective plants.

Seems to be a lockout......did you raise your phosphate levels this time around? Can lock calcium and check your ph!

is it the same plant by seed or are they clones?
looks a bit like over fert try giving just plain water. my 2 pence gd luck

Same genetic strain, Been doing so incase of overnutes but only getting worse.

Could Gnats do this to a plant?

Man that is either over fertilization or your PH is fucked. Definitely a lockout going on. Get some Epsom salts and foliar feed it asap.

What kind of lighting? How close are your light's whats the PH of your runoff

Salt buildup maybe? Try to wash the actual root mass off and give it 1/2 strength nutes and see what happens? And yes foliar feed with some calmag. Brown necrotic spots are normally calcium ime

What are your ppm and ph running at? Also have you checked your ppm meter for accuracy in a while?
theres borderline unsalvagable problems there. Looks to me like white spider might bites and nutrient issues bad. Id say thats a lost crop if you dont figure out the problem soo. I hope its personal lolz.
