problems with my coco grow

[gaiusmarius]

ec 1.0 is low, unless the plants are still very young it is no where near enough. i start my clones with ec 1.0 also worth remembering is that canna coco A+B is made to be used with tap water, it relies on some calcium in the water as well as trace elements. ec 0.250 is no big deal in your tap water. pure ro and canna coco a+b are not perfectly balanced, where as tap water and canna are perfectly balanced as long as the tap ec is not over 0.4, your 0.25 is really pretty damn good.

but to really help you you need to take pics of the whole plants, it's not much help to see a bunch of dead and dieing leaves, without seeing how big the plant is and how much healthy leaf it has what the healthy part looks like etc.

not flushing your plagron coco might be the problem. do a ec reading on the return. if it's crazy high you need to do a big flush with plain tap water at ph 5.8

cant spell true lol!!!

cant spell true lol!!!

^^^^ Very true g. I did forget that Canna is made to be used w/tap water, I think that's one of the reason I quit using their nutrients. I like to have complete control of what the plant is fed, and usig 250 + ppm's of who know's what is just too scary for me. Not to mention various contaminants such as cholorine, cloramine, and numerous pathogens contained in tap water which can cause crop failure. I still use their Canna Coco medium (loose in bag), Rhizotonic, and Cannazyme however (good stuff) Best of luck...

don't know what the prob with the plants is as i'm still new to coco but just to say i doubt that it's you tap water etc-my water is ec 5.5 (250ppm[x500])/ph 7.2-7.4 and i don't have problems with Canna Coco-or need any mineral suppliments even tho its a hard water area

could it just be that the Playgron coco is a bit 'hot'?

good luck

the plagron coco is the only coco i could get where i am , it wouldnt of been my first choice if i had been given one !
the water is not much different reading wise from england where all my other grows have been and i used canna everything with tap water there but the difference is with the limescale , it is forming everywhere ! my kettle needs emptying every few days as it if full of scale in the bottom , water heaters , my humidifier they all get f**ked in a very short time !
the plants are looking a bit better tonight after a bit of foliar feeding and i know the nute level of 1.0 is not alot but something is happening so i am open to any suggestions ?
befor in england i ran 1.2 veg and 1.6 flower with very good results and dripper fed every few hours , the then canna coco was flooded and flushed every time and recirculated .
it maybe the plagron needs to be mixed with some clay pebbles for airation and drainage ? that was my next plan !

i posted some pics of the size and whole plants in my original post , do you need some more ?

although i am not a total noob i feel one with my change of country so oppologise to everyone and thankyou all for your feedback and help,
it is very much appreciated and i am very glad i stumbled upon your community

i wouldn't have thought that it would need the pebbles-watering with ph'd water and a light foliar feed of nutes occasionally, as you are doing, sounds good-

i'm sure if you keep posting picutre updates peeps will keep comming with comments/suggestions

yeah if you feel there is too much chalk in the water, then get an ro filter if you can and use 50/50 ro/tap water, this will give you very good water quality and still supply you with some calcium and the trace elements found in tap water. my tap water is ec 0.300 at the moment and my plants tend to do ok.

my victory harvest...

white widow harvest...

thats with plain old tap water and canna coco nutrients.

nice buddage there gaiusmarius just had at look over on your dripper thread and it makes interesting reading !

just nipped all shitty looking leaves from my plants they where making me feel down , at least i can see clearly what is happening with the new growth .
still got nice white root growth out the bottom of the pots .

my ph here varies from 8.7 to 9.5 or there abouts and that is silly high as far as i am aware !

 

[gaiusmarius]

there you go mate, that's your problem. ph should be around 5.8 get some ph minus (phosphoric acid) and add a drop or two to the water till the ph is around 6. all your plants problems will disappear.

sorry i didnt explain myself very well , ph is that high before ph down

Howdy skin looks like the coco is still fresh maby just planted or not yet abused. When starting clones in rock wool i find the plants dont really get healthy until there roots have left the rock wool and well spreaad through your coco moist but not wet coco .. Use rhizotonic now and during veg in all feeds will improve root growth 100%, Your plants are not showing signs of fert problems so up ec to 1.3 PH 5.8 larger plants and stay at 1.0 for the seedlings. water once every second day until roots fill the pots(about a week) then if pots are dry or light after 2 days start to water daily until pots just start dripping larger plants, + before pots start to drip with seedlings in small pots.... Once a week plain PH 6.0 water or low ec 1.3ec or lower flushes can come in handy specially once your in flower or using PK...

In the base of your pot is there any perlite or clay to help drainage?? IF not maby alittle solution is pooling in pot keeping the lower of pot too wet. until roots get down there that can cause problems and rootsa will avoid until dryer..

LOL....yeah there ya go. Get that down and you're in there bro. going in or runoff that's insane high for coco. . 5.5 -5.8 is where ya wanna be. I know a guy runs even lower than that, but that's the safe range. You have ph down?

gaius.......that first pic....those buds really that blue or is that photoshop? and if they are that blue ....umm....she still around?:wink:

sorry i didnt mean i was watering at this ph !
this is before adding ph down !
i was just mentioning it as maybe a reason for the problem ?
i have had water at 7 - 7.5 straight from the tap before but never this high !

 

[Ono Nadagin]

that seems awfully high for the ph to be before adjusting ph... . do Canna nutes not buffer ph?... as far as I can recall every hydro nutes I have tried buffers to around 6.0ph... maybe buffer is not the correct term... the nutes all tended to take the ph of the solution to 6.0ish

 

[EddieShoestring]

i often read on these forums about complex interactions between various micro-nutes as being the aledged cause of plant probs when they've obviously been fried with nitrogen (mostly that guy sproutico i think) but if your water is THAT hard perhaps this could be one of those instances where this is the case?
If the concensus is that it is..then try another source of water for a short while and see if things improve.

Ono-Canna don't do a hard water coco nute-with ec about 1.5 and no ph down my nutes come in at 6.5 ish.

i have been thinking and i tried to grow some ladies in soil over here this winter , the cold eventually stopped play but up till then they grew fine !
the point being i boiled the water first , used canna coco nutes and used it slightly warm as to keep the roots nice and warm as it was -16 outside .
i had to cut them early as i just couldnt keep them warm but untill then they where growing fine and they where fed canna coco nutes with this water ?
the boiling of the water removes alot of the lime and things if my kettle is anything to go by !

 

[skin]

just tested a bucket of water and it was 8.8 ph and 0.6 ec straight out of the tap !
then i boiled it in a spare kettle i had in the shed and poured in another bucket to cool.

i took the readings again and this time round it read 6.7 ph and 0.4 ec !!!!!!!!!!!!!!!!!!!!!
this is a massive difference in my eyes and i am hoping the answer to my problems ?

i added nutes to 1.2 ec and ph'd to 5.8 and watered till it flushed out the bottom , now i will wait and see ?

wish me luck

 

[Guest]

ok....did you test the ph of your runoff water? 5.8 going in is good, but if it's coming out 7.5 you still have a problem. Very important you test the !!RUNOFF!! as well

 

[gaiusmarius]

good move skin, that should get them on track. next time flush without nutes and then add one batch of water with nutes when you are finished flushing. early on it matters not, but latter on you will be flushing to get the salt down. anyway, hope they perk up, otherwise you might really need to buy an ro filter? or buy or collect spring water?

 

[skin]

thanks for your advice gaiusmarius and old p much appreciated !

i will go down in a little while as the lights come back on and put a bit more feed through and collect the run off , it slipped my mind !
thanks again for reminding me !

does anyone use a r/o filter ?
can they give me any info on them ?
i have been looking at some but they have got very small tanks on them and they say you only get 15% good water max ?
does this seem about right ?

 

[skin]

hello there old peculiar i have tested the run off from the worst affected plants and i am not sure what to make of it ?
the ph has come through as 5.8 as i put in but this is really after the flush earlier so not sure if it was this earlier or not ?
but the strange thing is the ec finally settled at 1.4 and after flushing through the coco it has come out as 0.8 ?
have i been starving my plants ? wtf ?
surely it should come out as strong as it goes in or stronger if there is a build up !
any feedback on this will be greatly appreciated !!!!!!!!!!!!!!!!!!!!!!!
thankyou
