Undergrowth drooping top growth browning and getting crispy!

[jman2003]

Hi everybody. I've got some issues. Plant was fine before the holiday. I neglected it for a few days only topping off with plain tap water about a gallon a day. Wasn't able to take a good look until yesterday due to family staying over for Christmas. Notice browning and crispy leaves. Changed out nutrients for a fresh mix. Today it seems to have gotten worse. Undergrowth seems to be droopy now.
If anyone has any ideas as to whats going it would be greatly appreciated. Had issues with calcium deficiencies early in flower and a little calmag seemed to take care of the problem.

The tops like look some advanced deficiency, possibly magnesium, the bottoms look wilted from lack of water, did it dry out? what do the roots look like?

that plant is also a jungle and i would thin out some of the lower/inner branches, this will help prevent popcorn buds and mold.

Ive never grown dwc, but i have grown in soilless and hydro mediums and i would suggest a ph and ec meter in the future. they will help reign in the unknown variables.

The resevoir stayed full with top offs of plain water for 3 days. The tops looked nice and green 4 or 5 days ago. U think the mag deficiency go get that bad that fast? I feed it calimagic 5ml per gallon,wouldnt that help mag issues? I have a cheap ppm meter that reads 1500 ppms. Maybe it needs to be recalibrated. Gh ph kit has worked in the past for me. Guess its time to buy a meter.
Could i clone the lower branches i take off or are they too far gone? Thanks for the reply speed!

I think your over feeding the shit out of them if your cheap ppm meter is reading 1500ppm.. check your water without nutes to see if its even in the ballpark of calibration..

also. yes you can clone..

and what you wana do so they actually reveg faster. is. put the branches in a cup of water for a few days.. then into the medium unless your rooting in a ezcloner/aero cloner type setup.. then just put in.. but if u use domes.. don't use them for reveg cuts. just leave the branch in a cup a few days that will get them used to no dome.. then put into your medium and call it a day..

or you can air layer to ensure you don't lose your genetics.. so ud just follow instructions online.. and allow roots to form while still on the plant.. basically u can take HUGE clones.. and they usually always survive after u cut them off the mom..


your in HYDRO BRO.. the most important parts of your shit is PH and PPM. those should be priority for equipment.. grab yourself a FEW good quality meters. and be gentle.. and clean them all the time.. and you wont regret it.. this to me looks like ph and burning with too much nutes big time.

i run coco .. so i kinda know hydro .. just keep talking with me on here so u can get your post count up.. then u can start asking people in private messages for help so u can get direct answers quicker

 

[jman2003]

My water without nutes is 270 ppm i check it everytime i do res changes. Still probaly i shit meter though. I will look into air layering. I was gonna cut them and put them in a diy ez cloner. I like the idea of huge clones though. I guess i could dump the res and go half strength and see if that would correct things. I shoulda asked the wife for good meters for Christmas. Birthday is around the corner though! Thanks for the reply east coast.

 

[jman2003]

Im actually thinking of running just ph'd water to kind of flush it out a bit. Is this a good idea? If so how long should i flush before returning to half strength nutes?

 

[troutman]

Flush for a week just to be safe and then start very slow with the nutes.

 

[jman2003]

Got it. Hope this works. I only have another month to go until its finished.

 

[jman2003]

Things seem to have gotten worse. I dumped the res again and refilled with ph'd water again. All leaves are drooping. I will continue to dump res and fresh water dail to see if it helps. Should i dump hourly or is daily okay? Should i be using a flushing agent to expedite the healing? Fingers crossed she pulls throught this

 

[jman2003]

Speed of green had mentioned it looked like it had a lack of water. The resevoir has always been topped off daily and plenty of bubbles. I do agree that it looks as if its suffocating or something. Anyone have any ideas?

 

[jman2003]

Is it possible that i over watered them? I did keep the resivoir full to the top while family was in town and topped off daily for 3 days. When i say full to the top i mean maybe 3 inches below the top of the bucket. I just redid plain water again this time 2 inches below the bottom of the netpot. Guess I'll have to wait and see.

Are you putting 5 ml cali magic in the same gallon on top of your feed?
You got any brown or dieing on your roots? What do they look like?
I'd be real surprised if you said nice and white.

I doubt you are going to see major improvement at this stage of the game, more like trying to pull out what you can from harvest.

Im just guessing but it looks like too high of EC you was feeding shocked and killed roots. Looks like lack of water because they are probably fried and the plant cant uptake enough at this point.

How many weeks ya got left?

With hydro, if the PPM goes up, you are feeding too strong. If it goes down, you are feeding too weak. PH and water temperature are critical. Water should be between 66F and 72F. Also buy calibration solution for PH 4 and 7. I only used 7 at first, and when batteries went low, kept recalibrating to 7, but was wrong, that is why it should be checked at 2 levels.

Also make sure your airstones are not clogging up. This is an awesome guide. Read the whole thing when you have time. Quickly skim through it, looking at pictures, and see what matches your plants -

I wouldn't flush for a week.. that will not help.. maybe a single flush with 1/3rd strength or 1/4 strength nutes. but don't flush with plain phed water .. you will see lots of yellowing and growth will slow.

 

[jman2003]

Tony: i was giving calimagic 5ml per gallon on top of regular feed schedule. Roots are a pinkish orange color wich tjey have been since feeding started no browning or slime found as of last night. I'll check them tonight and get some pics up. Probably fried them as u said. I got 3 weeks left wich is of course when the really bulk up.

Loc: ppm usually didnt fluctuate too much which i thought was good. I give the airstones a cleaning weekly when refreshing resivoir.

Fingers are crossed she can pull through.
Thanks guys for replying and helping

what do your roots look like?

speed of on set could indicate root rot...

otherwise i had an issue years ago when a certain selection of a plant died and yours looks similar...it turn out to be a diseased limb that spread and killed the plant...

 

[jman2003]

Roots have a pinkish orange color. Thought it was from the micro nutes. No slime as of last night i will be posting pics later tonight when lights come back on. All branches looked healthy. I really think i fried them from not checking on them for 3 days while only topping off quickly with plain water while family was in town. Now i really hate the holidays.

 

[jman2003]

Well heres some pics of the damage thats been done. Im pretty sure its game over for me this round. Sucks!
Heres pics of the roots as well. They dont look bad just a little dyed from the color of the nutes but what do i know.once again any helpful advice or words of encouragement at this point would be great. Thanks to those of you that have chimed in. Fingers are still crossed and i will let everyone know what happens.

What are your reservoir temps?? Could reservoir been exposed to a lot of light?

Some people like sterile reservoir, others like live. For sterile, 1 drop of bleach per gallon. That might be good to try at this point. For live, google heisenberg tea. I am just going back to hydro now, after suffering with coco for 2 years. I have most of the stuff for heisenberg tea, like aquashield, great white, ancient forest, etc..
