Some of the leafs started to show disease or deficiency, and i have no idea what the problem is.

If I had to proffer an an opinion, I'd say that it's the early stages of a Cal-Mag deficiency. I don't know about Canna Bio fertilizer, but if it doesn't have cal-mag, then give it a shot with your next watering and see if it doesn't help.

 

[Davano]

Thanks for the reply.

I Do have Canna Calcium, but that just Calcium without the Magnesium.
can i use this or only Cal-Mag?

 

[Phytoplankton]

You could try the Ca only and see if it helps, if it works, great! If not, cal-mag might be better.

 

[Davano]

Thanks for the reply.

Will do that. Have to wait some days before i can water again. Soil Moisture is now at 63% i water when its at 30%
Will post a update 2 day after i give them water.

Might take little longer than that, but it should stop any additional leaf damage pretty quickly.

could add a bit of epsom salts, for the mag

Thanks for the tip!
Do you maybe have a idea how match i should at for a litre of water?

 

[Bounce3d]

i attached just a note i have, hope it helps.

 

[Bounce3d]

only thing is with the calcium nitrate you cant foliar feed, it will burn the leaves

 

[Davano]

Thanks for the replys.
This should definitely help

 

[Davano]

I have been feeding extra calcium, but the leaf damage is continuing.
Almost the hole plant is now infected see pic below, can it also be a iron deficiency? (someone give me this idea)
The trichomes on the buds look like most of them are now white.

bucket size is too small. the nutes aren't cutting it. ph is probably a mess and it locked. looks like it's flat in the drip tray and not elevated either. everyone else is looking better.

it stopped feeding at the roots and ate itself.
on the upside that plant is doing everything to finish it can.

 

[Phytoplankton]

If the calmag didn't help, I agree with bluter, you've probably got a nute lockout. I did notice the leaves are very dark green, so keep any additional N on the low side (since it's in flower, you don't need much now). The excess N may be why the buds are on the smaller side. I'd flush the plant with at least 15 gallons of water to re-set the soil. Then on the next watering restart bloom nutes and calmag. PH the water between 5.5 amd 6.2.

Its a autoflower, i have a 12 litre / 2,63 gallon buckets.
Is it not so that a autoflower in a small bucket starts to flower sooner then in a big bucket?
I have read that when a autoflower hits the bottom of its bucket with the taproot it will start to flower.
That's what i read in internet, please correct me if i am wrong.
The drip tray had 4 elevated square in it (will post pic below)
The nutrition i am using is Canna Bio, it has on the bottle then you don't need to PH you water.
Then plant takes up the right amount of nutrition its needs, its very hard to over feed with bio feeding, or i am wrong with dis?
I have a other autoflower same bucket same nutrition and both whent in to the buckets at the same time, it has zero problems, but its bud are not as far developed as the one with problems. will post pic below of the buts of the plant with no problem.
I also have 2 mother plants but they are feminized plants, but also no problems.
I am a amateur when it comes to flowering, have had mother plants for 2 years with canna bio never had a problem.
I am definitely not questioning you experience, just what to be sure.

Don't have a lot of experience with flowering, did not notice the but are small, but i do have to say they are really dense.
Will wait on a reply on my above reply, if its needed i will def flush the plants.
Where i live tapwater is good to grow with.
To flush the plant i need to fill the bucket to the top and then wait till it drains and then fill it up again and then do this with 15 gallons?

If you go to this link and click on 3 a Bio Canna you can see the nutrition i am using

go with 5 gal buckets. they will benefit from the larger root structure.

the fabric pots are good, but need to be elevated above the drip trays to be effective. ph problems are common with fabric pots sitting flat in the trays. it won't matter what ph you water/feed them. they can't sit in stagnant runoff.


also you should ph to media. unless LOS i'd ph. there's always one plant that can't run straight water. i like control, so i choose media where i control the parameters like ph. or i'd run LOS.


that plant didn't blow up on it's own.
the rest are good though.

edit : you could use a big light upgrade judging by the buds on the rest at this point.


more edit : not a big fan of canna bio either. yours look better than others that post with issues in that line

Never heard the taproot/autoflower thing, I’m doubting it in my experiences. Dense is good! Those are inorganic nutes so there is definitely a chance of lockout.

Do you mean 5gallon pots? He’s already using 12 liter bags.
