[justanotherbozo]

mornin' bro, sorry i don't have a direct answer as i'm no expert.

to me it looks like some kind of nute lock-out.

anyway, here is a troubleshooting form for you to fill out, just
answer all the pertinent questions so, when an expert happens
along, they will have as much info as you can provide.

btw, this troubleshooting form was compiled by Rusty Trichome
over at can.com so he deserves the credit, not me.

sounds like you really need to fill out that troubleshooting form bro!

and do a google for 'Stitch' or 'MyNameStitch', she is an expert in
mj problems and has a thread over at ICMag i believe.

personally, i have her book to refer to when i have a problem.

for real man, fill out that troubleshooting form and then post it,
with answers, in her thread, if she can't figure it out, your plants
are dead.

 

[med.botany]

wow that's weird lookin...i dont know about pest's but it could def. be some kind of disease..i've seen that taco'ing from underwatering and heat stres but it there could be something wrong in the roots system..Try using some Revive from AN..

here's some info bout it...Ever had a crop damaged by heat, stress, insects, bad fertilizers, disease, or other grow room problems? Revive is the perfect crop repair formula for times when your plants are suffering and need immediate help. Loaded with safe forms of iron and other rejuvenating nutrients, Revive can save your crop and give you a successful harvest instead of a total loss.

peace HV

 

[Highlander]

I've had a problem that a lot like yours and I added some cal/mag at 5-10ml per gallon and my girls came back to life real fast...I had that burning look where the leave curl up and pointed but I wasnt burning them and I cut back on everything! bombed in case of pest and It was still showing that burning look until i added the calmag!

high bro, just so you know, i'm not accusing you of bein' a noob,
i'm sayin' i'm a noob, ...it's me who's unqualified to help you in
any way other than to point you in Stitch's direction, she
really knows her stuff, like i said, she has a book out.

...btw, i'm not a total noob, i've been running a micro-SOG
for about 2 years now, ...so when i say Stitch is an expert,
it's not total bullshit.

...oh yeah, i posted that troubleshooting form in an attempt
to help you bro, ...the more information you provide,
the more likely you'll get an answer you can use.

Thats sad to see HV!

Don't know how to help, damn!

Which day are you at?

Mine all look good. Had some pH issues with my coco plants, but they came back and everything is looking good again.

I would try something to clean the rootsystem like others mentioned.

Talk later

 

[can-i-hit-it]

dam man sorry to see the girls hurtin are the tips of the top fan leaves turnin black if so its the light it kinda looks like heat stress i would let the lights up and feed wit just plain water and see how they react if that not it i would try the cal/mag sombody already recommended

 

[HappyHybridS]

Hey haze :)

Damn that looks shitty :( are you sure your ec-meter still does the trick? pics 4 and 5 look like the worst nuteburn i have ever seen... but with ec 1,4 they never could be burnt like this...

other possibility is a virus... but i really hope it's the ec-meter...

are plants from all strains concerned?

have tried 2 diff ec-meters.....all ok..... the plants look great and in 4 days all is over.....it's at every strain

the roots are white and healthy, no pest in the cocos....


if i can't stop this.....
i have to cut down 3 grows..... :mad0233:

next i try to foliar spray them with H2O2 solution
..... if it's some kind of bakteria or fungus......


peace HV

Hi haze ventura...

I ve had this kind of problems a few times.

For me it was :

- some kind of fungus/bacteria, which i treated with some products containing anti fungus : Myclobutanil , to be found in gardening shops

http://img181.invalid.com/img181/3467/tofs019800x600be7.jpg

- pests, called Tarsonems.. really hard to get rid of them... they are so small you can only see them with a microscope, and you have to wait them to move to see them... i can see trichomes/spiders/thrips without any lens, but not those...
the main problem they cause are leaves deformations, and no bud growth...

but i ld say the fungus should be your problem... hope it helps....
