It's anyone using Canna Coco A+B?

I’ve been using Canna Coco nutrients for a while and pretty much follow the Canna schedule. I ran out of the Coco A+B nutrients recently so bought another 1L of each. But I’ve noticed that previously my water had a base EC of about 0.4 to 0.6 and if I added full strength it would get to about 2.0 which is correct. Around the time I started the new bottles I noticed that my water base EC had dropped to 0.2 but now even mixing full strength (4ml/L of each) I’m only just getting to am EC of 1.0. the plants seem ok but I’m worried I’m under feeding them. I’ve got a perpetual style going on so there’s plants at different stages. I’m also using Canna PK13-14 and Rhizatonic, and also Bio Diesel Calmag and bat-pooh booster but these are added after and don’t affect the EC much.

So my question in has anyone else found this recently with Canna Coco nutrients? I’m wondering if there’s a weak batch. I’m using a Bluelab truncheon that’s less than a year old and seems to be functioning properly.

Im a diehard canna fan. Really hope they arent diluting their products, but a lot of companys have done this with their products unfortunately. I havent noticed anything. You really need to add boost to your lineup. Its hella expensive, but im telling you, it bulks and frosts them girls up biiig time.

Did you get them from Amazon? I’m super careful now because some sellers are selling a counterfeit of the products I buy. It’s possible also I guess that the product could have been improperly stored which could be an issue.

Yes, ive got 5ltr of canna from years back 1ml/1ltr =1ec with the new nutrient i bought im getting 0.5ec for the same?

I’ve since been looking at other options I’m not buying canna again.

Some might say its a copy or something but both worked great so im not buying any excuses.

I use Flora Flex dry nutrients and their coco now. I go by their no added calmag chart and it’s been good for me.

That doesn’t sound right. My water is 0.5 (+/- 0.1) generally.
Topped off res last night. 10L of water. 1.5ml (might have been 1.8ml p/L) of A&B got me to just over 1.5ec.

Edit - just to add my bluelab truncheon started saying everything was 0.8 no mattter what I put in a bit back. Grabbed it one day to stir a mix and it was red hot. The batteries were too hot to hold. That was about 18months use. They’re based in New Zealand so I just bought a cheap probe rather than argue about sending it back.

@douggyfresh420 I hope so too. I’ve done a couple of runs with Canna Boost but like you say it’s crazy expensive. I switched to the Bio Diesel equivalent which is a fraction of the price. I watched a YouTube video about Coco a while back (I’ve searched for it again since but can’t find it) and the guy was saying that with Canna Boost there’s a wide range for how much to add, but anything over the minimum is wasted. So whatever stage you’re at, if you’re following the feed schedule just go with the minimum amount and the bottle will last longer

@Itslegalnow it was from a local grow shop, they are quite big so have good stock turnover. My regular shop was out of the 1L bottles so I went there instead. It’s possible that heat affected it somewhere in its life as it’s pretty hot here. I’m planning to get some more from my regular places and I’ll ring and let them know.

@Star_Dog ok, good to know, thank you. So I’m not alone and not going mad if it’s happening to you too! So what did you do, add more nutes to get to the correct EC, or follow the feed guide and have a lower EC??

I’m thinking to bite the bullet and buy the 5L. It’s the first time I’ve ever had an issue with anything from Canna in over 20yrs. I’ve seen good results from Bio Diesel Green Diamond a&b of your looking for an alternative. It can be used on anything, not just Coco, so it’s more flexible. Thanks for the info.

If you’re in the UK then Shogun nutrients are the new go to for coco, more concentrated feeds and a superior finished product

@LumpyMashedTaity thanks for confirming. I’m at the PK stage and mixed up a bucket with 6L of water. The feed schedule says 30-40ml per 10L of water, so that’s 3-4ml per L so I added 6 x 4ml = 24ml of each a and b which should be full strength, up to about >2.0ec but it only got to about 0.8ec.

Thanks for the truncheon info, I’ll keep an eye on mine but they’re usually solid, unlike the pH meters which seem pretty fragile.

@Bush_Dr thanks for this. I’m in Australia now, when I lived in the UK I used to use Canna mostly and sometimes Bio Nova, I had some nice results with those. I’ll have a look at Shogun. Cheers.

I adjust the ec as required with a blue lab truncheon I don’t follow any schedules as such.

Fwiw buying in 10ltr makes a big difference to the price per litre, it costs circa £40/45 for 5ltr a+b for 10ltr a+b it’s only £55/60 delivered.

The last nutrients i bought was 20ltr Ionic 1 part bloom, my plan is to veg with the remaining canna and flower with Ionic, for convenience sake i like one part nutrients and I’ve had good results with Ionic.

Give Dyna Gro a go guys, marketed under the Superthrive brand name now, its cheap, good and no calmag needed for coco.

If you are in Aus I highly recommend Anarchy nutes.

Super clean and stable. I run RDWC systems but keep my mums in coco. Anarchy goes hard. I also recommend crystal clear from bio diesel, but don’t bother with the rest of their line. (ohhh except aloevate, that shit is killer if you do foliar feeds)
