Leaves pointing downward

[kenned]

hi.

I'm having some problems with my cannaplant.

Ïnfo:
Indoor
hydro, eb'n flow
strain: a cros between g13, hashplant and citral skunk.
fertalizer: GHE one part
pH: just around 6,0
µS:between 900-1000

The thing that troubles me is that its only one of the plants that grow that way, and they are all in the same bucket..

The first picture is of the best looking plant, and the others are of the sick/strange plant..

the sick one..

What you guys think??

 

[Core]

2 much water cycles??? ohw and those ppm's are way 2 high for that plant...looks like she only can use 500 a 600 ppm's....

 

[kenned]

Well core.. Thats the thing I dont understand.

How come 2 of the plants can't handle it when the other 2 can??

(and is 1 µS the same as 1 ppm?)

Different strains require different food and care.

Your plants are locking out some nitrogen and since you got 2 different strains in the same bucket you are going to be fighting the entire time; the only good time to use more than one strain in a setup is if you have grown them before with the same nutrient reqirements and know how they can handle the nutrients.

I would get them into a different bucket keep the strains seperated if not you may have a tug a war the whole grow.

900 to 1000 ppms is crazy!!! for that size of plants........ are you using tap water by any chance? if so get rid of it because you need to use RO filtered or some other water because that plant has nitrogen isssues and it's either from the clones taking a while to root or there roots are not getting to the food.........

Still 900 for that size you will burn them 900 ppms should be for like 4 foot tall plants

 

[kenned]

yes, I'm tap water..

maybe I didn't expres myself clearly enough.. I am only doing one strain...!
thats why I think its so strange.

Actually, I changed the water-cykle last night, and already this morning the leaves wasn't pointing that much downward any longer. I wil try and change the levels of ppm's (to a thinner solution ofcourse)..

thanks for the help, Maybe I will post a picture later, of how the plant has changed.

best regards and thanks for the help..

same strain or not.....not every plant is the same...and also the size of the plant depends and rootsize may vary as can seen on the pics....Nway hope you get'm rocking again....

 

[kenned]

Core--
I'm sure I will..
It's going to be a seed grow, so they have to make it..

this is a pic of a clone from the plant that I'm gonna make seeds..:

But thanks a lot for the help!! Really appreciated..

I wouldn't trip over the fact that one is doing better than the others. Not only do different strains vary greatly in how they like their nutes, different phenotypes can also.

I agree with stitch, though 900-1000µS is 630-700 ppm at the .7 conversion. That still sounds high to me for small plants like that. Some people pull it off but for most of the strains I've grown, I'd usually have it closer to 500-700µS, or EC of .5 - .7, sometimes even lower when they're that small.

once they get a def or lock-up (what i think happened) then its less able to process and grow whereas the other is still accelerating.
looks like it needs more oxygen do u have a airstone in ur res?
(sry didnt see mention of it)
also try using a little h2o2 in ur res to prevent rot and help the lil'n get some extra oxygen.
it will kill the benes so re-innoculate when done...

*edit conside using RO water 'by the gallon' they sell at stores (for 50cents a gallon) around here...if you only have a 5 gal or smaller res its retarded to use tap.

 

[Frozenguy]

i would clone the plants doing well and make a mom out of it.. monster maybe??

 

[kenned]

the plants are doing better. Maybe not much better, but better.
First pic:

The two big plants are the ones that are doing fine, and the two others are not doing so fine.. (the one ine the right corner is the one from the previous pics..

I think the small ones (and now the big ones too..) have problems with some kind of deff, maybe thats why its growing so slow...?

unfortunately I'm still using tapwater, as I dont have any chance of getting the R/O-water.

I have raised the µS to about 950, and the pH is 6,5.

I think it might be needing N or/and P..

What do you think??

best regards,

your going to get an algea prob with that clear lid man

when observing the photo, clawing of the fan leaf tips are evident, meaning the plant has slightly more nitrogen than it needs. adding more N will hurt it.

also, i believe the symptoms may be from a less than optimal pH. a 6.5 is a bit high for hydro in many cases.
you could try lowering it slightly to about 5.9 - 6.0 and see how the plants respond. it may be difficult to lower it to that number because you are using tap water. a lot of municipal tap water tests at 7.0 or beyond due to the residual dissolved solids like calcium carbonate, NaCl, magnesium, etc.

for the water issue, i suggest trying this link:
http://www.icmag.com/ic/showthread.php?t=55810&highlight=diy+reverse+osmosis

this will give you water with a starting pH of around 6.0
and for best results, let even this water sit for at least 24 hours before using.

i hope this helps and best of luck to you.

forgot to mention that a phosphorus deficiency usually, but not always, is indicated by purpling of the fan leaf stems and purple streaks on the main stem.

 

[kenned]

Thanks cloud strife!!

changed my pH to 5,7 and my EC is about 0.9...
now my plan is to wait a few days, to see what happens..

Thanks for the link to. I may buy a R/O filter on ebay, if I can find one for the right price...

Thanks.

i may have something that will help you. i read a thread or somthing by PipeDreams, and he bought a "Mr. Clean Auto Dry Car Wash" kit it makes the water on the car dry "spot" free by removing the disoved solids in it he tested the water that come out of it and it was under 50 ppm so he disasembled it and made it the way he liked it (or you could use it as is!) and that is his water filter for less than 30 buck and it performs quite well and its flow rate is that of a regular hose almost (RO filters do about a gallon in fifteen minutes look in the 150 club for the instructions i think its by PipeDreams

new problems with the little ones..

I sprayed them with a spray to eliminate thrips, and I just gave them a good, big spray.
Could this spray have caused this?

 

[lynz420]

I don't do hydro myself, but that kind of spotting is usually a sign of major pH fluctuation.
I have never seen spraying cause leaf damage like that.
Good luck, I hope you are able to get it under control

 

[kenned]

When you say major pH fluctuation, what is it then??
Because the pH have not changed much over the last 1-2 weeks.. And when i say "not much" I mean its like been between 5,5-6,0.. Or maybe thats too much of a change??

thanks

 

[lynz420]

What method are you using to test your pH level kenned and how often are you checking it? I wouldn't expect to see leaf spotting like that if the pH stays in the range of 5.5-6.0. It takes more of a wild fluctuation for the leafs to become spotted like that. Any chance that your meter is not properly calibated?
