Plants dying rapidly week 5 flowering!!!

[SpiritualHealer]

Hello, first post constant reader on rollitup. I really need help from somebody quick!! My hydroponic garden has all gone droopy yellow and dying. The leaves are looking terrible and its affecting most of the plants in my garden. I believe the plants may have gotten a bad watering during one of the cycles, with a very high ph. I gave them a good days flush yesterday with no visible results today. I'm using using AN three part with Big Bud liquid, and some Dutch Master Zone.

I have recently slid bamboo stick down the sides of the pots for bud support and thought it may be root damage also. But its also affecting a plant with no bamboo. Some plants also seem fine. Should dying leaves be removed?

If its not in the water, its lights/temps or ventilation

Do they get a fresh supply of air from outside? They look like they cant breathe.

What are you growing in? hydroton, soil?

Lord! that looks awful. Wish I could help Dude, but i'm a confirmed "dirt" farmer. Major patio grow each summer and a little indoor cfl/dirt action in the winter in my son's old bedroom. Hope you can turn that problem around.
Good luck & good grow.......BB

Man, whatever happened to your plants is terrible. May I ask why you are using the Dutch Master Zone product since you're already using AN lineup? Perhaps you are dosing them with twice the recommended (possibly more) with rootzone protecting products? Dutch Master Zone's chosen weapon of choice against pythium and other root problems is mainly sulfur. I suggest reading your labels very carefully and making sure you are not inadvertantly harming them. Btw, I use Zone as well in my nutrient solution, along with hygrozyme, and the Dutch Master Gold line nutrients. So far, so good. Best of luck with your next batch. IMO, those plants are toast.

Those plants are definately suffocated, plus a little dry. Whats the temp and humidity?

I don't believe its the water since I just changed it a couple days ago and I follow the measurements on ANs website, and I use a light dose of Zone for the garden was showing signs of Pythium.

I'm using 1 1000w HPS and the temps stays around 85-90. I do have an intake from outside and can filter recycling air.

I am growing rockwool into Hydroton.

Well, I'm using the Micro Grow Bloom with Big Bud and the local hydroponics store recommended using 1/2-1 Tsp per gallon of Zone to help wil a slight Pythium problem I noticed about a week and a half ago.

I've put a lot into this project. You don' think there's anyway I can save them!! We're so far!

If you have outside ventilation and you temps are reasonable then there has to be something wrong with your nutrient solution.

Start with fresh R/O and add a very small amount of nutrients like 5 ml per gallon. about 200 ppm. Calibrate your PH meter, PH it to 5.8 and water it man.

I would just turn the pumps on for at least a couple hours. Making sure the water doesn't hit the rockwool cube if you have one in there.

There is something stopping transpiration, again it looks like they cant breath or they are not getting water.

My friend toasted 10 plants, when I got there they looked like this and it was 110° in there.
I save 4 of them by doing what I just said. It took a day or two.

I think I saw you post recycled air, get fresh air to them.

Thanks a lot for the help man. It definately does appear that they aren't getting anything almost. So run drippers straight through the hydroton for like 2 hour with light solution? This wont overwater?

Also as far as lack of transpiration. As you can see in the pictures some of the leaves are pretty much shriveling to a crisp. All the leaves that are drooping badly are green and dry. The older fan leaves are apparently turning yellow also. I was wondering if it could be a lack of humidity? I currently havent been doing any sort of read on the humidity and am thinkin i may need a humidifier.

Another wierd thing is its really only affecting the big girls of the crop. Most of the small ones seem to be completely fine. Thanks again.

No man, As a plant goes through its life cycle it needs humidity and gives off humidity. When its young they could use some but as they get older they produce it. Well, when thing are going right.

The girls in flower, don't worry about over watering them at this point. In flower they need more water and the Ph should be slightly higher for best nutrient use, like 6.1 or so. My girls in hydroton get 4 hour water cycles.

What I would suggest is flushing with a mild nutrient solution for a few days maybe a week. Then just a bit to get started back.

Once they are back stay at half strength until you can find how much these girls can take.

Hey man thanks for all your help +rep. I going to take your advice and get them on a longer watering schedule with lighter nutrient content. Up to this point I had only been giving them 3 15 minute cycles a day.

What do you think about think about giving them 3 15 minute normal nute cylces and 3 20 minute no nute cycles a day, or some sort of balance like this( I only ask because I've got a full rez with nute solution and I could easily bring in another one with pure water and do this).

Well hopefully the girls can recover for a good harvest, I've put a lot of time and effort into this and there are many patients in need.

I've attached a few pics of some of the buds! God damn, I hope they make it... they're so damn juicy!!! Pic 1&2- Purple Erkle x Trainwreck Pic 3- Jack Herer Pic 4- White Widow

Nice idea, but don't you think the second cycle would cancel the first by washing the nutrients away? sounds like it to me. After the first watering you ppms will start to build in your clean res and eventually balance out. I would think it would be more of a pain in the ass then a benefit to the plants.

Personally I believe the plant needs the water when the lights are on not so much when they are off. I run a 4 hour cycle starting two hours before lights on and one hour 2 hours before lights off.

What I would suggest and most pros do is flush for a day between water changes. It gives the plants a chance to expel salts that would otherwise end up in there feeding solution.

Looks to me like you weren't watering often enough at some point to support the largest plants. I say this because you say the smaller plants were fine. I think you should flush and clean quickly, find the right nutrient level again don't keep it too low for long and cause more problems. And then just water more often next time this start happening again.

How often and for how long do you water? Drip system or ebb and flow maybe I missed that?

Thats a good point. Definately going to start flushing once a week before water changes and just keep increasing nutes slowly until I find the perfect solution and watering cycles for my girls. One more question, should I hold off on switching to ANs Overdrive? I was planning on switching over very soon.

Thanks for the response. I'm pretty sure I've got i got it figured out thanks to cruzer 101. But heres the rundown anyways. Up to now I had only been watering for 3 15 minute cycles a day! And within a matter of 1-2 days they looked terrible(pictures in original post). I use a drip system.

I would hold off a week or so to let them catch up, Then just do it in small amounts (1/4 strength) at first. I found you really cant over water hydroton, you can over water the rockwool cube when its small root system but once your in hydroton and just watering the roots, Na.
Some guys run there water 24/7 Personally I think it needs time to dry.

So, Let it flow bro!

Move them to soil.

Wait, your combining NUTES???? Dude this is a big no no unless you know exactly how they are going to mix... they all have micro nutes in them that are sometimes not even on the info with the nutes. they will create spikes in the amount of the different nutes. Which WILL result in over nute . This will not be good for the plant as you can tell. look i know you just want the best for your plant but stick to one nute for veggin and one for flowering

What like token soil?
You are not going to make very many friends here with comments like that. We try and help each other here.

Yeah man I understand and I was. I actually got the suggestion for the mix from a local hyrdostore worker once I notice a pythium problem. I guess I should go yell at him he told me to just add it to the mix

.... but hopefully quick response will lead to quick recovery. I still have a lot of faith in my babies.
