Leaves curling down like a canoe

[Kush09]

Out of over 20 plants, I have only two that have leaves curling down; like a upside down canoe. Note - All other plants are doing fine except for these two. They are just under a month old, and grown in soil with correct ph water. They have not been fed water or nutes for days. What are symptoms of leaves looking like this? Well it appears I can't post pics yet

Maybe they are wilting?
Lift their pots to see if they are significantly lighter than the others - if so - water

Maybe lay off the nutes for a while, maybe these two are more sensitive - do they have thinner leaves than the rest? If so - sativas require less fertilizer than indicas - thin leaved sativas will curl under if overfed.

If your soil is wet, let them dry more in between waterings - sativas especially do not like soggy roots - it suffocates them.

Good luck -

he isnt feeding them any nutes. Id like to know though because some fan leaves on my Banana Kush are doing this same thing

It is very hard to diagnose without photos. I do not grow in soil but I will try and help a bit.

What type of soil do you have them in?
Are the plants a very dark green?
Are the leaf TIPS curling down or the whole leaf? (it's called a Rams Horn).....(but Canoe works too)

IF..... and I say IF.........the leaves are dark green and the leaf tips are curling down and under like a rams horn you have a Nitrogen Overdose.

If your soil is too hot for the young plants there is not much you can do except water with PLAIN pH adjusted water. Do not feed with nutes for now. As long as its not actually burning the plants, they will eventually grow into it.

IF your soil is not to hot and you have been feeding with extra nutrients when watering...........STOP. Flush with PLAIN PH adjusted water for several days to a week to allow the plant time to use up whats been fed to it.

Either way there is a simple rule that has saved my ass everytime: "When in doubt......Flush it out".

Hope that helps,
Pirate

Eagle claw is the term we always used.

I think of five things.

1. Nitrogen overdose
2. General nute overdose.
3. Incorrect ph
4. Rootbound
5. Cold temps that kill off small roots.

With more information we could most likely help you find out which one it is.

Good luck..

I agree with the overfeeding.

Please fill out the Infirmary form and post pix for more/better help.

Any time release nutes in your soil?

I have to disagree with Pirate and flushing hot soil. If the soil is hot to the point of burning, you must transplant, not flush. Flushing won't work and may make the problem worse by releasing extra time release ferts each flush.

Been there, done that.....

Vapour, post a thread and we'll help.

BTW, he said he "hasn't fed for days"...not "hasn't fed at all". It's what he fed days ago and before that we are interested in.

like they said rams horn/ the claw is usually caused by too much nitrogen or a phosphorus def. slow down on the feedings till you start seeing a nitrogen def. then you can start feeding again at medium strength. look on the internet for jackerspackle and Nietzsche. they have guides similar to stitch's sick plants. but with alternative diagnoses. nothing wrong with stitchs guide but i disagree on some of it and for those i go to the other 2 sick plant guides.

Wow, thanks everyone for all the informative posts! With you guys help, I believe we have this figured out to be a nitrogen overdose. The soil is a mix between miracle grow(never again), a local mix of peat/verm/perlite, and fox farms happy frog, with added perlite and dolomite lime. I fed the plants when I transplanted them from 3" to 2 gallon pots. I used Pure Blend Pro, Liquid Karma, Epsom Salt, and Molasses. I used the amount of Pure Blend Grow on the label for the vegetative stage. I now believe I used too much, too soon and should have only used maybe 50% strength. This may be where the nitrogen overdose has come from. I will next water with plain correct ph water. Luckily only 3 plants are doing this. The rest have dark green leaves, but they are not curling. I will post pics when I am available to so everyone can see.

More info:

-Plants are from bagseed
-The leaves are very dark green and look glossy or shiny
-Leaves started at first by the center curling up, and the sides pointing down
-Leaves are now looking like an eagle claw with the sides and tips pointing down
-You could also describe the leaf as a canoe turned upside down

I had this same problem with a bag seed plant

I treated the plant the same as Satori yet no problems from the Satori

My guess was a N overdose but I wasn't sure, I would love to know the answer to this

 

[whodi]

what about having him feed with bloom nutes only... no nitrogen.. since potassium and/or phosphorus help use up more nitrogen that's stored in the plant?

That's what i did with my clawed up plants at one point and it seemed to work.

 

[Weedhound]

I'd transplant into fresh quality soil myself.

good luck.

Most likely you did or do have a nitrogen overdose. just so ya know as requested)

(Weedhound) I'd transplant into fresh quality soil myself. good luck.

If possible.........this is good advice. If not possible, Do what was suggested above. Use PLAIN PH adjusted water until you see a slight Nitrogen deficiency before resuming a normal nutrient feeding program. That could be a couple weeks or more if your in soil. And start re-feeding slow. Better to be underfed than overfed. Overfeed and it could do permanent damage. Underfeed and you can always add more.

The others that are VERY DARK GREEN, are on the edge of an N overdose. Don't feed em till you see them turning lighter. (using up the N)

Thanks again for the help. I will not feed again for a while and see how things go. I will just use this soil and hope for the best since this is only bagseed and I have some dutch passion master kush and twilight on the way. I will only be using Fox Farms quality soil for the next grow. I will also not start out nutrients at full strength when plants are young.

Well, the plants recovered and everything has been going good. I have just been using plain ph'ed water. The plants were transplanted into a mix of Fox Farms Happy Frog cut heavily with peat moss, vermiculite, perlite, dolomite lime. They are now over 2 weeks into 12/12 so I fed them yesterday with Pro Bloom, Liquid Karma, and Molasses. I fed them at under 50% strength to see how they would do. Today, I notice that on all the plants, the leaves are doing it again! The leaves have only done this when I have added nutes! Please help, what is going on? Surely I didn't overdose at under 50% strength?

 

[stihgnobevoli]

that just tells you that these particular plants arent heavy feeders. slow it down. instead of making sure they stay full, just feed them when theyre hungry. you dont eat when you arent hungry do you? why should you treat your plants any different.

So STOP adding nutes! Simple fix eh?
