Hey Guys!
Im planning to make the switch from Terra to Canna for my next run. Can anyone be kind enought to share a feeding scedule for an 8 week hybrid grow? Or is your recommendations to just follow the "light feeding" schedule in the canna grow guide?

Starting from scratch with a new strain, got a few years of growing experience but im no expert. Got the enviroment dialed in and running co2.
Early veg 3-5ml per gallon
Late veg into flower 8-10ml /g
Calmag 5ml /g first 4 weeks
Then 2.5ml /g
Pk 13/14 week 5
Overdrive week 6-7

Been using that schedule I found online for a year or so and its great. I also use 5ml /g growmore liquid seaweed all the way through and 1ml /g floralicious once or twice a week.

Thanks Gemtree!
Great, simple one.
So, you go 8-10 ml/gal (total 16-20 ml?) for the whole flowering period and feed every watering? No feed-feed-flush-regime?
Please, tell me why you prefer Advanced and GH addetives before Canna?

Yea it's every watering just 8-10ml /g of equal amounts of a and b. I do around 150-200ppm calmag first to buffer my ro water then it all comes to around 800ppm in flower and I go up to 1000 ppm sometimes before tips burn. I just use overdrive for the slight pk boost and it has all the amino acids ,vitamins and stuff the floralicious does but less nitrogen.

Rhizotonic is just mostly kelp with the same aminos and all that so liquid kelp is good and the growmore is $22 a gallon so way cheaper.
I've tried boost and it seems like the same kelp/floralicious/superthrive shit so not needed either. Oh I also dust roots with bioag vam on transplant so no myco needed either.

Used cannanzym for a while and dont see a difference barley pond enzyme is the same and cheaper if you want to use it. Idk works great for me never nute burn and hardly ever deficiencies my buds are always on point. Any other questions hmu glad to help.

I just tried the new nutrients out... Got a problem.
Blended 10ml each of a&b to 4 gal + calmag and ended up at 0.7 EC @ ph 6.2. So far so good. But when added (full strength, 60ml for 4 gal) Rhizotonic the solution jump up to ph 7.6-7.8. To push it down to 6 again the PH- increased EC to .8 so I tossed it. Remade the solution with only 15 ml of rhizotonic to not need so much PH- (N).

Have you had the same experience?

I've been having to use a lot of PH+ with the CannaTerra which use to end up @ ph 3.5 when all was blended without additives, but it did not seem to be a problem for the plants but this much PH-
Really?

Using RO water at 0.0 ec, 8ppm.

Before I started using Canna line I spoke with the folks at Canna USA, told them I was using RO (12 ppm) because my tap is around 800 ppm. They recommended that I add tap to my RO and bring the ppm to around 120 prior to adding nutes. I am not sure what is in my tap so I use CaliMagic and Epsom to bring my ppm to ~ 120.
Not sure why you adding Rhizo to the mix increases the pH so much, have not had that issue.
My RO system adds Cal and Mag back to the water for flavor, total 51 ppm,

I read here:

http://www.canna-uk.com/rhizotonic
-Set the pH of the nutrient reservoir after adding RHIZOTONIC as it will slightly increase the pH

Might be because I'm really low in nutes, perhaps?
The base is super acidic and if I go full Rhizotonic but half base nutrients the PH whill probably be very high.

First time growing in coco ( mother earth 70/30) and using CANNA nutes in 5 gal fabric pots. Been hearing different things on how often to water w/nutes. With 5 gal fabric pots watering until full saturation; should i be watering every day or every other day?

Depending on your stage of growth, you eventually will want to water multiple times with nutes at every watering. Low rates of nute.
Remember Less is More! Be sure to watch for Cal/Mag issues.

Hi guys
Just got me some
canna a+b, rhizotonic, cannazym, cannaboost and canna pk.
Still gonna get some ph- and some callmag.

Do you feed nutes every feeding?
Or do you feed,water,feed,water ect

And do you use the chart on the canna site?

Nutes every watering. Here's the chart I've been using just use the rhizo instead of seaweed. file (1).jpg

Oh add 150-200 ppm calmag to ro water first.

So here is my cannacoco ( canna-terra) dilemma:
I just picked up my growing hobby now that it’s recreationally legal in my state. I really am searching for the quality and quantity in my grows. I have use the General hydroponics flora series About 10 years ago for a few years and now again I recently used it. But with all the advances that have come in 10 years nutrient line wise I decided to Really look into better nutes , better lighting and even switched to from soil to Cococoir . What my question is do you or anyone reading this have a practical feeding chart for canna coco A&B ? I just started auto flowers and am about to sprout my next round of phenos also. So if somebody could please contact me and give me an idea about this question it would be greatly appreciated. Since I ramble I’m looking for a practical feeding chart for canna Coco a+b. And with auto flowers I would assume to cut the amounts in half or even in thirds

Thank you
