7 and 8 weeks plants die overnight?!?! Any help?

Hey,

Well I've just lost an entire run of Mekong Haze almost overnight. It started last week. One day after feeding, I had a plant collapse like it had been starving for days. I thought I had made a mistake on the PH and that's what killed it, but now this week, two days ago, all the rest collapsed. Then, another plan in another grow room did the same thing. Has anyone seen anything like this?

I suspect that the heat may be building up, but other plants in the same area are fine. The other plant in the other grow rom is in differn media (SuperSoil) and a different age. Both sets of plants were fed the same food as other plants and the others are doing great.

Any help?

those pics make me misty eyed. i would be angry, dude. id probably cry, too.

Oh man, sorry about that.

Closest thing Ive seen is Ive had a few critical mass plants do pretty much that, 99% sure it was a cal-mag def let go to long because I had skipped lime on my last soil mix. It started at one branch, cut it and would then move to the next. Did not happen to the entire plant all at once though.

I have had this issue outdoor, its the strain not handling the cond. All seemed well until the sun got really hot mid summer and within a week my plants Some up to 12 foot withered ,yellowed and quickly died. Cost me about 20lb, ive now eraticated the pussy strain and replaced it with better strain, no worreies now. I feel this has happened to you bro but with that mekong strain. It seems that diseases just take over the plant quickly ,if so it will brown and die .

Yeah, I was a l little suspicious of the genetics. the other one that collapsed was S.A.G.E. And sour which is a very delicate plant I've found. My Qrazy Trains are still kickin ass though, no matter how hard I hit them they just keep growing stronger. I guess I'll chaulk this up to a sensitive strain and to much heat. We saved what we could but I didn't even see trichomes on them, while my mother plant is full of seeds and trichomes, same age, same food, same medium, but different area. Much cooler. Probably just make some hash out of what I saved, maybe some budder.

Sucks but oh well, it was a single seed tht I cloned the hell out of, and I have more seeds now. Thanks guys. Smoke one in memory of my plants. Now, into the seed vault for my next run!

What did you feed them? It doesn't sound like it was anything outside of your normal schedule

I looked very carefully at your photos, and I would say that this is not Fusarium Wilt as there is not the usual chlorosis spotting on the leaves [older, that is]. I suspect that this is Fusarium's evil twin, Verticillium Wilt [VW]. Like Fusarium, VW is a fungal infuction that enters the plant through the roots, then becomes systemic via the plant's vascular [xylem tissue]. Once infected, the plant cannot be cured, and when the infection reaches a certain point, we'll call it critical mass, the plant crashes literally overnight. The only way to prevent VW is to use sterile soil/media, sterilize the seeds and apply fungicide to the soil during the vegetative growth period. Sorry about your loss.

I aggree with the above diagnosis. Its a Wilt. Doesnt really matter which one. It all means the same thing in the end. Death. I just lost my entire outdoor op due to this.
I just feel empty inside.
