Possible CA deficiency, or PH issues???

[GrnMtnGrwr]

GeorgeSmiley - I would never go back to soil. I LOVE coco, the consistency is 100x better than soil IMO.

lysol - I've grown in coco several times before, I've completely read Rez's thread, and h3ad's thread. You can overwater coco if the root system is too small. I and countless others have confirmed this. Put a seedling in a 2 gallon pot and water it every day, and then tell me you can't overwater coco. There are many different views on runoff and how much to do, but it is by no means necessary. I know how DWC works, and it's a completely different situation. I appreciate the input though. ... Also, while the 6/9 is a great starting point, it is by no means the ultimate solution. Every plant is different, and different plants have different needs. I think that is clearly illustrated by the equal treatment that these plants have received. Maxicrop contains very few nutrients, and I used a diluted dosage.

Mixing up a batch of 6/9 with nothing else right now, PHing to 5.5, and watering them.

 

[GeorgeSmiley]

Yeah I did some reading and wanted to add that it looks like you can overwater when the seedling is very young compared to the container.)

So at first you should water at the stem and slowly water out from there till it takes hold then resume watering it every day etc.

It is what it is but It's alwo minor and you're getting help on it so I think it's be a transient problem.

Hoping for the best.

Thanks GeorgeSmiley!

I just watered them, mixed up half a gallon of nutes which was perfect. Half a gallon is 64oz, and I had 15oz of runoff, so a tad over 20% runoff.

Here's the whole group, there's some healthy looking plants in there for sure.


And here is #6, #7, and #8...



#6 and #8 are droopy with no other signs of problems. #7 and #10 aren't quite as droopy, but they've got that spotting on most of their leaves.

 

[GeorgeSmiley]

If it's not pest then it'll sort out, maybe take a few extra days to shake it off but they'll be growing like mad soon.

All you can do is watch. Have you seen any bugs whatsoever in your grow? Just curious

Hope I'm not blowing up your thread?

 

[GrnMtnGrwr]

Not at all George, I appreciate your posts!

I've kept my eyes open for bugs but haven't seen a thing. All I can do is watch.

I think they will really be taking off soon.

 

[GeorgeSmiley]

Yeah mie were still looking pale etc after I took care of the bugs and then 1 full feeding and some supper cropping they are great! I got bugs back so I'm treating now and will feed in 3 days or so.

I doubt your problem is bugs, seriously doubt. But I throw it out there. I'm going to be following this one really close.

Good work. I hate grow diaries where the first page or 2 is nothing but I don't got a camer, i'm missing my batteries etc, I like the side by sides especially when you sex them you can go back.

 

[GrnMtnGrwr]

I love going back and watching how the grew to the point they're at now.

 

[FoCo(No.Co)]

I'm going to have to try this soon. I'm just curious because if it's a problem with nutes or pest they would all be affected or none right?

At this stage, all the plants could be infested by pests but only two show symptoms. But if it is pests, all or most will eventually show symptoms.

GreenMountain, I'm sorry to say it but that does look like early signs of a root aphid infestation. Its hard to tell though, because the symptoms are the same for a lot of other things.

 

[GrnMtnGrwr]

I'm reasonably sure it's not pests, but you aren't the first to mention it.

Any preventative you'd suggest? When you look at those most recent photos, what is it that makes you think it's root aphids?

lysol - I've grown in coco several times before, I've completely read Rez's thread, and h3ad's thread. You can overwater coco if the root system is too small.

So you're just going to let your plants dry out for days at a time.... And you wonder why your plants got problems?

 

[lysol]

Yeah I did some reading and wanted to add that it looks like you can overwater when the seedling is very young compared to the container.)

Only if you don't know how to drill some drainage holes Coco only holds a certain amount of water. It doesn't matter if you have 8oz or 8 gallons (unless you throw it in a bucket with no drainage/don't let it drain).

If that weren't true how would people flood & drain, or run drip systems? Water daily. Period.

And in h3ad's own words, if you sprout seedlings in 2 gallon containers you're an idiot. At that point you are just going out of your way to kill the plant, just to win the over watering argument.

Only like 1/10 people actually try to say coco can be over watered - https://www.icmag.com/ic/showthread.php?p=2545821 (and I suspect that is due to shitty "pith" quality coco). Also I could see these people not waiting for all water to drain/setting the plant on flat ground where there is still standing water inside the container. Its the container that gets you, not the coco.

Regardless, even if coco could be over watered, you should not let it dry for 3 days. That is your problem right there.

Also read this thread http://www.icmag.com/ic/showthread.php?t=130535. In post #10 he shows that canna says to water daily. He says after he flushed and watered daily all problems went away.

 

[GrnMtnGrwr]

Show me a seedling in a large amount of coco, watered daily.

Are your plants seedlings? In large amounts of coco? Does constructing extreme conditions to intentionally kill plants change the fact your plants are drying out?

 

[GrnMtnGrwr]

You seem to be ignoring the fact that they've looked like that, without change, through two waterings. And yeah, they are still seedlings, and their roots were small compared to the container size. I'd consider them seedlings until they have their first mature leaves, which is where they are right now. And their roots are now filling the container, which allows the switch to contant watering. I'm speaking from firsthand experience, but please keep telling me I'm wrong.

You're saying that coco is impossible to overwater, and I'm saying you're wrong.

 

[lysol]

You're saying that coco is impossible to overwater, and I'm saying you're wrong.

No I'm not saying that. (becuase "overwater" is a stupid concept)

The only way to overwater coco is by not watering it enough...

[GrnMtnGrwr]

You cannot over water coco.

Did I misinterpret that?

...and while I respect h3ad more than most, I don't take any one persons advice as the final say. At this point it doesn't really matter, because the plants are entering maturity.

 

[lysol]

You can deprive it of oxygen, but not "over water". Is that a hard concept? DWC growers grow IN water.

Sure letting the coco get dry is ONE way to improve oxygen, a dangerous one. Watering more increases o2 too.
You said you water every 3 days, and got these results. Why not try watering daily like most coco growers (and like the manufacturers recommend)?

All the people who said it could be over watered were using unrooted clones. Your plant has roots.

Why don't you just try this? Take one of those suckers out of the pot. Look at the bottom, look at the sides.. do the roots look like they are rotting? Do they look white and healthy? Is the coco in the middle dry? wet? .. are the roots concentrated in the bottom where it is most wet? In the middle where its dry? In my experience the roots stay & thrive in the wettest parts. I use containers with really good drainage and I "drip them dry" (give them a few good shakes too, while holding at an angle to drain off all stagnant un-oxygenated water) after each daily watering.

 

[GrnMtnGrwr]

We're not talking about fucking DWC. The only period I was waiting 3 days between waterings was when it first broke the soil, when the root was barely there. I use containers with really good drainage and drip them dry too. Thanks. I appreciate it.

I watered them yesterday, I watered them today, they look the same. What's the problem?

 

[GeorgeSmiley]

Shits gonna sort it self out in a week as it ages and takes water nutrients well. You're doing bangin

Thanks for taking the time to document. I was going to grow these but went with another c99 flavor instead so I'll grow these through proxy... you

[Wasabi420]

im also using coco....so your saying you should water coco daily?? even if its not dry? Ive never heard this but I might try. Would it matter if I mixed the coco with earthworm castings and pearlite, and if I did should I still water everyday?
