Need some help asap dying plants

I'm a newbie and even though Ive done alot of research Ive ran into a problem with my plants dying 1 by 1.Its a Hydro system,clay pellets,recirculating.The leaves start by wilting over a bit,then more and curling inward like they are folding up or loosing their juices until all of the leaves dry up.I thought at first they were not getting enough water because they were the ones on the ends,but now it seems to be spreading.Ive encountered the dreaded spider mites but have been on top of them,no webs,they die off and still seem to come back but I dont think thats whats killing my plants.Ive posted 2 pictures,1 of which is almost gone and another that seems it might be starting,showing how the leaves look at first.My PH is around 5.8 .Is there a disease spreading or what? I cant loose my whole crop,I just started flowering into the second week.Someone help my babies please!!!

never seen anything like that first pic. there are some good threads here describing alot of plant maladys with pics. keep searching the forum under plant problems. good luck bro!

What size of grow area are those in? Maybe the picture(s) are misleading to me but it seems like they are quite cramped in there...

Bueler,Bueler,...anyone.....anyone....
Somebody has to have seen this before. The leafs are nice and green when this starts to happen,first the tips start to point down,then it continues up the leaf until it eventually rolls up and dies but the leaf stem is still sticking out...,and they stay green until they dry up and turn brown.
Wheres the Doctor Phil of weed when you need him?

I'm thinking over fert or too much watering. I would cut foliar feedings and see if that does the trick. Also what is humidity at? Probably over 50% huh? Try looking up moisture stress and see if anything lines up. Remember anything you do will take a couple days to show improvement or worsen, thats why you shouldn't do more than one thing at a time. Good luck

wat do your roots look like dats wat mine looked like wen i had root rot iam new at this to but my plant looked just like that

My guess is over fert (too much N most likely) or, if your roots arent shiny white then root rot

Good point on the roots fellas that would definately have an impact.

I'm using clay pellets so the roots have a brownish tint from the pellets,hopefully thats what I'm seeing.My humidity is 44,temp in room is 74-77.
How long does it take for root rot to come around? Ive been veggin' for about 8 weeks trying to make sure the spider mites were gone.I did a flush with only water 2 nights ago.Should I change my pellets out to fresh ones to be safe? Ive came too far and all was good until now and hopefully I can save the rest.My flowers are coming in pretty strong at this time.

Ok,thought I had this under control and I'm getting bit again.Here's another 2 pics.This is what the ending of the plant looks like,this time is 4 weeks into flowering.WTF!!! There is another plant right next to it in the same tub with absolutely nothing wrong with it!! Is this what spider mites can do or???? Ive been battling those little f**ks and they keep coming back,then gone,then back etc. Im using "Safer" bug killer.Ive flushed once already and thought thats what is was,Im following GH feeding directions and using only ,cal mag,micro,bloom,and kool bloom.PH is 5.8-6.0 (yellow) Where is the Doctor Ruth of weed when you need them?

Here's 2 pics of the problem.

Good karma will come the way of whoever helps fix this

i've had that happen before. some sort of ph induced nute lock out. mine didnt recover. got pissed so i switched to dirt and have had no issuse since. i enjoy hydro, but dont have the time or energy to keep up with the constant monitoring. and buy a digital ph tester. HAnna makes a decent one for around $15-25 on ebay.

ur roots should not be brown flush out with ph water and h202 and ur gnna c dead root cme off

...my first view of your plant indicates fert burn (curl under as such). Use neem oil for the bugs. Are you using RO water in your res? Do you know your ppm/ec?

Looks to me like way too much nitrogen. Some plants just don't like that shit. These plants are definitely showing you what I refer to as (as do many) "The Claw".

The Diagnosis: Too much Nitrogen lead to over fert and nutrient burn.

The Prognosis: They aren't dead, but they aren't going to produce either. Your best bet is really to kill them off and to start over. If you see these through you won't get a decent yield and it'll just be a waste of another 6 weeks. Get some new little girls veggin' up real quick and get back on track.

Oh those poor girls! They look awful! Something's going on with your roots. It's either the bugs and/or over-watering and/or you have a fungus. Get a magnifying glass and start checking things out. I've had soil mites and they make the leaves not only curl down, but also make the margins curl under like yours, AND the infested plants don't have has much foliage...just like yours. Make sure your canopy temperature is not too hot, water with some H202, and treat everything with imidacloprid. Good luck!
