Anyone know whats wrong with my leave

[Ph 007]

Hwre they are today look a rad better since few days ago see how the feeling to the auto pots being on and e.c of 1.2

 

[jguit]

They do look like they're greening up a bit.

Make sure your feed pH is stable. Let your feed sit for a few hours after you mix it up and check the pH again just to be certain it's not rising/falling out of range.

 

[Ph 007]

Then thses 3 in veg tent been in total 1.0 e.c and no calmag for 3 fsyd todst and look much better then other ones euth Calmag , I just dont get it, even my two water info sheet in post above showes theirs no calcium or magnesium in my watter but yet these 3 in veg no cal look great but many tieme in the past no calmag I get problems

 

[Ph 007]

I see all sort of conflicting answers and answer with no supporting evidence.

I'm wondering how often you are watering, and what sort of runoff you are getting? I'm also growing (first time) in coco coir, and my plants have grown at an amazing rate.

I can't say what is causing your issues as I just don't have enough experience. I can contrast with my grow, which you can see in the post 'Explosive Growth in Coco Coir' to see how it compares to you.

Here are some things I think are fine in your case as they mostly match my experience.

1. RH and temps: My RH was high in the veg state (around 60%, higher at night when fan was off). Temps at 79-84F. Those seemed to be ideal veg state conditions, and my plants exploded in growth.
2. pH - based on advice from a number of sources I have set my pH at 6.0. I use a Bluelab controller to keep it at 6.0 in the reservoir. I use Silica Blast as the first ingredient in my fertigation mix, and it notes that pH should be set to 6.0 for that product. 6.0 seems acceptable across both veg and flower, and .... it's working for me.
3. Lighting - without an actual meter reading, we - and you - have no real ID what you're putting on the plants. Curling edges might be a symptom of too much light, but overall your plants didn't look scorched to me. Give us some sort of actual measurement please, lumens, LUX or PAR.
4. Coco coir type - what's in the pots? Homemade? buffered?
5. Cal/mag - exactly what have you been doing here?
6. Nutes - a bit more detail please. I started mixing nutes in RO water, with starting EC of 60 (my scale is micro siemens, so 1000x yours). First I put in 2/5ml/gal of Silica Blast, and then I wait an hour. Next is Cal/mag. I started out at 2.5ml/gallon Calimagic, but have dropped to 1.9 in flower, going my GH chart. This brings my EC up to around 350. Next I add the GH nute trio, which gets EC up around 1200. I then add a couple of supplements, Floralicious and Koolbloom, which gets me to around 1350EC. A bit of humic acid (DIamond Nectar), some Yucca powder as a wetting agents, and finally 2.5ml/gal of 33% h2o2 to keep the tank clean of algae. I mix up 10-11 gallons, and the pH comes out to about 6.1. I then put a bit of pH Down in it and dump it in my 14 gallon reservoir. I then usually top up the tank to 14 gallons with plain RO water to drop the EC a bit. I still have a bit of tip burn on the leaves, so it may still be a bit high.
7. Watering cycle - in veg, I started with 3x daily feedings, with 10-20% runoff. As the plants grew, the runoff quit, and I needed to go to 4x daily. When the runoff quit again, soon before flowering, I increased to 5x/day. In flower, recently, my runoff EC started going up and up and up - to as much as 800 points higher than input. So I went from 30 second feedings to 35 second feedings to increase the runoff. In 4 days the runoff EC has dropped until it is now about the same as the input.

My initial guess on your plant issues is that they may be seeing a deficiency rather than an overdose. To me it is really hard to tell. But the color is a little light, indicating lack of nitrogen. The curling might be a calcium deficiency, or maybe ... ? Hence I am wondering how often you water them. My feeling is that with more waterings, you can (and should) use a lower EC, and you should judge the water quantity and input EC based on runoff EC.

By the way, my pH doesn't change much in runoff. Still 6.0-6.1 usually. I don't measure it much, but I measure EC in almost every runoff.

That what if done to these

Led grow 18 hours light veg
Day temp 80-82f
Night temp 77f
Humdiy 60-70%
Growing in Coco
using canna coco nutrients
Ph 5.8/6.0
Tap water thats 0.2e.c I add canna calmag agent to bring that tap water to 0.4e.c every watering then add my feed they where on 1.2e.c total then I tried 1.4e.c for 2 feeds then 1.0e.c for 2 feeds, I got a feeling it's either humidity or maybe something to do with my feed and calmag

And in normal use baged canna coco medium and nutrients , but had no canna coco medium in the shop so i used below coco

Word of advice.. If something appears to be working, stick with it, Don't keep changing things by the day, that'll lead to failure. If after a few days, things are looking worse, re-evaluate.

 

[Ph 007]

They do look like they're greening up a bit.

Make sure your feed pH is stable. Let your feed sit for a few hours after you mix it up and check the pH again just to be certain it's not rising/falling out of range.

Ye i mini flushed last night remeber
I took my 0.2e.c tap water to 0.4e.c with calmag agent then added 2.5ml cannyzm and 1ml rootonic and 0.5ml a&b Total fees in was 0.7 top fed and out was 1.6 s9 deffo a salt build up today they looked greener since that mini flush last night, I should really of fed that another 2 days i reckon as run off was high , got feeling 1.2 now may show over feed soon see in a day 2 I'll post a update

 

[Ph 007]

Thanks for all the help guys

Also can anyone work out what that oily look in pic above in tray at bottom of pot is?

Re: badly twisted leafs and tips .. Is it possible you have introduced some kind of chemical to the environment? Cleaning agent?

Edit: updates look better

No nothing just cal mag and canna coco feed line or nutrients

 

[Ph 007]

Here's the canna feed chart i had when I bough my nutrients
Iv tied following this chart but they e.c is to high I get N over dose following it

They calmag ageng also contains Nitrogen aswell for some reason

 

[jguit]

Look at the EC Total on the Feed chart you posted.. You should be anywhere in between 1.1 and 1.8 EC in veg since you're starting with .2 EC tap water.

I think you're on the right track at this point. Looks like you were feeding too lightly.

I still dont think it'd hurt to let that big 20l container of coco to dry back a little and let the roots do their thing but as i said, dont change anything if things are going in the right direction.

 

[Ph 007]

Here they are few hours later they do not look happy since turning auto pots on to bottom feed automatic and fewd is just 1.2

The looked happier asmorming and the niht before i top fed at0.7 as a mini flush and out was dam high at 1.6 so deffo was over fed I should of flushed more,

Tomorrow I'm gonna flush the wholly shit Into them with just plain water and ph it to 5.8 , and I'm gonna flush toll out and read a about 0.2e.c and then ill make a feed like this
Take my 0.2 tap water to 0.4 with calmag Then add my feed till I get 1.2e.c then ill feed them that, so I'll be starting again get all the shit out of or pots,

The leaves still feel like paper dry
And the seem to be having some sort of transpiring issues if I said they correct lol,
Reason I think this is I check my leaf temps today and room at 80-82 lead temps are 75-79f
And I tested earlier room temp at 78-80f and leaf temps read the same as 80-82f.

Some pics just taken

They don't look to bad in the pics buy-in person deffo look unhappy

Not sure if you can see it but the pic my tiger is pointing at is starting to 2-tone iv had this problem mamy times in the past nearly every grow 1 aide the leaf is light other is dark it's only just stated happening so not that bad yet, ow the fun, in use to like a little play with them but this is taking th biscuit lol may be back to soil in futre coco stressing me out

 

[Ph 007]

Can this stress cause them to tuen hermi when they are in veg still?
I know flower could do but in veg I always wondered

 

[Ph 007]

I wonder if this is my problem messing with my nutes, reqd below about sodium with my water contains



using softened water as it adds sodium to the water and that's bad for the plants


^
Someone else said the same earlier in the post water softeners



Iv Been reading this post
They also mentions about N over dose in flower that's with calmag with just a N of 2-0-0
My canna calmag agent is 5-0-0 I think, so more Nitrogen in mine, if often had N ovwr dose in flower and iv dropped my nutrients low and kept the calmag going and still got worst

What's is this shit you are seeling us canna ,

 

[steamroller]

Have you turned the lights down any or raised them ?
My Calcium [ Jacks this time ] is 15- 0- 0 and I never lighten up on N because of it .

 

[Ph 007]

100% over fed / lookout

I just flushed them with just ph water in was 0.2e.c, out was 1.0-1.2e.c
I had to us h 10-12 litres through each pot to get the e.c down to 02/0.4e.c crazy man

Iv only done 4 plants making food another 4 after food then.

It's been such fun in the water park, i hope one day I can do it again
I give me self a electric shock I tripped my electric , I got water everywhere and I got ph down in a cut on my finger

Lights are dimmed to 150w and 50cm away

 

[Ph 007]

I'm gonna feed then 1.2e.c in a hour
But debating to add calmag or not
If got 3 plants in my small veg then they been in no calmag for 4 days today and the look bloody awsome
The on total 1.0e.c so thats 0.8+my 0.2 tap water

 

[jguit]

What size containers are the plants that look good in?
