PLEASE HELP! My girl just turned on me!

[Shaun1says]

Hello all!

let me quickly ge tto the point because this is urgent. I have 6 plant GDP and SSH in a rubbermaid DWC one week into flowering. I had a plant that was recovering from a PH inballance and overnight it pooped on me. Im sure your saying "pooped??"

Pooped:
-Weak stems bending over
-All leaves limp along side of plant
-lifeless look to it

I have already checked the roots and they appear to be white, slightly bone color but not enough to be alarmed of. and just FYI and am using Supernatural brand nutes aqua gro currently but changing to aqua bloom and super boost

There was nothing that happened to it that should have done this what could it be???

Thank you all

Can you take a few more pics and make sure they are a little bigger and are not sideways

I can't tell very good what is going on due to them being small not able to enlarge them and because they are sideways.

Do those plants have there own res? like they are in a big tub with air stones?
What color is the roots, also where did you get the questions you just posted, the ones you answered the questions too, where did you get it from?
I have one, but there is more questions I ask, this one is not in detail so I am wondering where you got it from.

your going to have to pull that plant and put it into a "nursery". You dont want that plant in your sog with the problems that its having. You wont be able to isolate and cure the problem while its in a dwc like that. Just a personal thought on this, i would actually take that plant out and put into veg again. Simply get a 5gal bucket, drop the plant in there and start with straight water at first and then slowly bring the nutes up. A solid DWC flush wouldnt hurt either, just get some Hydroclean or something similar and let that run for about 4 hours and then add about 50% nute strength. Your seeing your plant go into a lockout so your going to have to basically "reset" that plant.

Get some better pics that are not sideways, and that we can expand a little bit more, but the key to dwc is being able to pull the plants that are having an issue out and get them to run alone. I know it seems strange but sometimes plants wont get the needed nutes that they need cause the others are taking them. I have seen this first hand and its a strange strange issue, especially when the rest are fine. The other thing to watch and this does sound really really strange but it can happen, is that your over watering that plant even tho its in a dwc.

The good news is that you can still save it, bad news is that it wont be part of your sog for this round, but at least you have a mother......

Hope that helps.

they are all in just a 6 gal tub with 2 16" airstones running under all the roots.

It appears to be spreading to the plant next to it so now that I have heard a bunch of reasons why this is happening what can I do to stop it and make them healthy again??

Here are some pics today of the bad one:







And here are some of the plant next to it, since then the other one the other way has started too. . . please help me

Honestly, it looks like a pH issue that started a lockout and now your one plant is fried. Looks similar to a nute burn, but you say your roots are not brown but white. Do your roots have the fine hairs on them or are they just the larger roots? Take a pic of the roots if you can that will help also.

How much nute to how much water?

Your ph looks out, those strips are not very good. Try to get a digi pen to test ph.

Next time don't combine different strains in one rez, they all have different needs and you can't properly take care of them like that.

How much nute to how much water?

begining 2nd week of flower following a 40 hour flush is:
1 tsp supernatural bloom aqua
1 tsp spernatural grow aqua
a smidget of supernatural super boost

all that to just under 5 gallons of water

lockout? could someoe tell me anymore on what this is? what causes it? and hw to cure it???

thanks a ton

 

[HeadyPete]

Lockout is when the ph of your media is out of range (5.8 - 6.8 - 6.3 is ideal). This condition keeps the nutes in the media from the plant. Even though there are nutes in the soil, the plant cannot use them.

At 6 and below, P, Mag, Cal and molybdenum become unavailable, this matches real world experience with my garden. Above 7 ph and the micros start to lock out.

 

[Shaun1says]

Thanks for the info guys

I went to my hydro shop today and got a hydrogaurd and superleach samples and he said those could help a bit. Also does anyone know about overwaterign in a DWC setup?? I have 6" rockwool cubes (I know we too big but worth it cause the GRAND DADDY PURPLE clone came in it ) and it is constantly at least partially in the water. Could this be causing my problem??

thanks again guys

Thats for soil. He's growing hydro. 5.5-6.3 is range with 5.8 being ideal.

 

[MynameStitch]

What color are your plants roots? Looks like there is multiple problems here.....For a plant to look like that the root system has to have been affected....... what is your water temps?
What are you growing in? A tub? Is it light proof?

 

[HeadyPete]

Sorry I disagree. I've heard more theories here on ph and after all the info I have read I've settled on my numbers for hydro or soil. All the research I did, all the charts I've seen backs that up. Heads magazine confirms my numbers as well, please explain to me how hydro is different and why the ph should be so low. I'd really like to hear a good reason once and for all. please show your info/sources, GrowTime. Thanx.

I see your chart and Ill raise you a chart

Ive only ever seen the 6.3 ph as optimal for soil and 5.8 as optimal for hydro here on IC since this is the only place I go for grow stuff. Am I a scientist that has tested it thoroughly thru scientific method? Nope. Besides, I use fulvic acid supplements (and only grow hydro) so ph doesnt matter too much to me personally. Just stating what Ive always seen. Id be curious to see what you've read that made you decide that hydro and soil have same ph ranges.

 

[HeadyPete]

Well for one thing I have a copy of Heads and it is a hydro issue and they state to keep ph at 6.3 for hydro.

It is a real head scratcher for me....like you I just know what my garden likes, but it was that mag article on hydro that threw me off.....might have to go through some back issues of HT and CC and see if there is a consensus....

The other prob with your hydro chart is it shows P and Mag unavailable below 5.8, so do you find that to be an issue in reality?

Honestly, I think the key is to allow the ph to swing around throughout the entire acceptable range, at least in hydro. Keeping it pegged on one spot, be it 5.8 or 6.3, isnt doing the plant any favors in the end since uptake does occur for different elements at different ph. Ive also grown some decent plants with a hosed up ph meter that was reading .5 too high so who knows.

Btw, the chart is just one thats been floating around here since I joined. I didn't make it.

 

[HeadyPete]

I understand you didn't make the chart. Google "ph nutrient chart" for images, there are lots on the net.

The mystery continues......
