Help with wilting coco plant.

I'm at about 2 weeks in with my coco plant. It's in a 6" square pot. I have about 32 total. All of them are growing nicely except 3of them. 2 days ago I noticed one wilting. Yesterday still only one wilting. Now today it's 3 wilting. I'm wondering could it be something going on with the roots?

Only nutrients I'm using is H&G coco A/B at 7ML per gallon. And calmag+ at 5ML per gallon. Using tap water. Ph is around 5.8-6.1

Here are pics

Any help would be greatly appreciated.

How often are you watering them? How much are they drying between waterings?

Can you take some pics of the healthy plants for comparison?

By 2 weeks I assume you mean from clones?
 
What is your light source...I would also say that the total ppm for plants that size based on your ml dosage would be pretty high.
 
If you know the PPM of the irrigation water & run-off that'd be great but I assume yon don't have an EC meter which is why I also didn't ask.

My gut is that is that Fatleg77 is probably right. It's mostly likely got too much salt in the medium & it's reversed osmosis drawing water out of the pot. The other less likely possibility is that it's over watered & suffering from a bacterial wilt. That's a lot less likely though

Switch to pHed tap water (5.6-5.8 for coco) and soak them until you get a bunch of run off. In the second picture they look a bit dry.

Also how new are these clones? To successfully run hydro you have to have a pH meter and a TDS or EC meter otherwise it's nearly impossible. Further color changing drops won't work they are not precise enough. You can find cheaper meters on eBay.

I water once a day. About 600-700 ml . Yes 2 weeks from when I got the clones.

Here's pic of healthy plant and also pic of one of the dying plants roots.

A 1000w hps. After I get done mixing nutes my ppm says 750.. I feed plants and collect run off and ppms are about 860.

Just pH tap with no nutrients? I got the clones about 2.5 weeks ago. I have a TDS and pH pen? Thanks

Yes, I could go on but now just get them nice and wet with good run off. If you want to check the TDS of your run off that's a good idea and make sure you calibrate your meters for accuracy. What is the TDS of the nutrient solution you have been feeding them?

This may sound stupid but it's best to confirm right off the bat; the wilted plants are wet right, you know it's not wilting due to water/heat stress? I assume that's a given but assumptions make an ass of u & me.

So if they're wilting while wet & it's not a response to extreme temps (stomata close at 30°C to protect the plant), without an extreme EC difference between irrigation & run off, with the pH in a good range; my next suspicion would be over watering (doesn't look like it based on those healthy white roots) or a bacterial/fungal problem.

I would isolate them as a precaution, water with a 3% hydrogen peroxide & start searching for potential pathogens that mimic your symptoms.

I run exclusively coco/perlite and they look way to dry from my experience. Usually it's the simple things.

Edited to add: That's not entirely true. I'm running a mix of coco coir and coco pith right now because I potted up some orchids and use coir LOL but same difference.
 
If it were me I would flush back to under 100 ppm and then give a low dose of nutes ( like maybe 250 ppm tops)and wait for them to bounce back
 
Also I would hold my pH tight at 5.8 in veg and then 6.0 in flower

Here's another question I have. I only feed once a day. If I'm putting 500ml into my 6" square pots and I'm getting back around 250-275ml runoff . Does this mean the Coco is too wet for another feeding?

Depends on the coco, good quality coco (long fiber) can be run straight like rockwool & be kept wet constantly. If it's prone to compaction then constant watering will create a low oxygen enviro that can lead to pathogens. Perlite obviously helps & also cuts the cost down. Just keep an eye out for signs of over watering & air on the side of caution if you don't know. Better yet is try a couple different ways to see what works best.
 
I'm not sure how coco works...I use promix hp plus about 20 percent more perlite and I water every 3 days without issue. I have heard of different coco mediums and they seem to have their own characteristics depending on their quality and additives. No matter what medium you use you will have to learn it's ability to hold water and for how long as that will ultimately determine when you should water/feed. After that is figured out then you have to learn how much nutes your plant can use without burning it. I'm 7 weeks into flower of my first grow and I have just started to feel like I have anything figured out...lol. but I am in a comfortable cruise control now

promix is primarily peat moss.
