I use BioVega, BioFlores, and BioBoost along with a few other things. I don't use the Rhizotonic. I use Roots Excelurator and Hygrozyme. I like them better, and have had pretty good results with them. If you didn't wanna fork out the big money on Roots Excelurator, you could use BioRoot from GO. It is cheaper and works really well too.
I feed every time. In veg I use 15ml/gal of vega all the way to flowering, and in flowering I pretty much stick with 15ml of Flores every time except for during weeks 4-6, if they look like they want more. If you notice your plants aren't taking up the nutes, I will throw in a little water towards the end with some mycorhizzae or a tea to help chew up whats left.
I don't ever pH my nute mix. I add dolomite lime to my soil which helps buffer my pH, and on top of that I add my teas which help keep my pH in check.
I used to build a light soil mix using Pro-Mix as a base, but I've actually cut back to just using Pro-Mix, Dolomite lime, and Azomite. I didnt like the drainage of my mix and I started having funky issues, so I went back to the aforementioned mix, and things are turning back around. I guess I"m not as clever as I thought I was.
-Some things to keep in mind while using BioCanna. These are all from my own experiences and subject to change.
My grow changes every run.
1.)
Water Quality: One of the biggest improvements I added to my grow was a water filter with carbon filter, and an aerated reservoir. If you are using chlorinated water, you are killing your microherd, thus you get build up since all the nutrients aren't being broken down. I use a Small Boy filter with a KDF-85 carbon filter for dechlorination. It runs around $170 and is worth every penny. Store water in a drum or garbage can and be sure to aerate it well. These work well for city water, and well water applications.
2.)
Cal Mag: BioCanna doesn't have any, they expect you to get these from your soil. I don't run a charged soil, so I have to add them in however I can. The first way is through using lime. I like Dolomite lime because it has both cal and mag, whereas hyrated lime has low levels of magnesium. If you don't want to do this, you can use GO Cal mag @ 5ml/gal every watering. Really though, make your life easier, add in some Dolomite lime @ 1 cup/cu.ft. or 2 TBS/gal. I topdress 2TBS every 4 weeks after transplant, and mix it into the top of the dirt and then water it in. If you don't wanna do this, the GO Calmag works really well, but I like to take out just about everything I can from my feed schedule to make it as simple as possible.
3.)
Trace Minerals: BioCanna doesn't have any of this either like lime. I use Azomite mixed in a 1cu/cu.ft. or 2TBS/gal. This normally last me until harvest, but I will also use Earth Juice Microblast @ 5ml/gal every 2 weeks if I don't use azomite, or the plants look like they need more trace.
4.)
Supplements: 2 things I've found BioCanna to be lacking in are Nitrogen and Phosphorus in flowering. To counteract this I start using Natures Nectar Nitrogen when I see early nitrogen fade, (yellowing of leaves,) which normally starts at around week 3-4 of flowering. I use it until week 5-6. Use as little as possible. If you put too much into your plants, getting that nice color fade at the end is impossible. For phosphorus, I use Budswell liquid 0-7-0. I start using it when the plants look like they want more phos and use it all the way until the end. I use 1 TBS/gal. I do use it up to 2 TBS/gal, but it will burn my light feeders, so be careful and be sure to check your plants. My heavy feeders love it at 2 TBS/gal though, just be careful, and use your own judgement. In the last 1-2 weeks of flowering, if I still have a lot of green in my plants, I just run the Budswell with some honey and bio boost. I also use Dark Energy to get Amino Acids, and Floralicious + as my humic and kelp extracts. My plants love them.
5.)
Microherd: I used to use all kinds of expensive powders and stuff to reinnoculate my plants and keep the beneficial bacteria and fungi thriving. You really don't need all of that. Brewing a simple Earth Worm Casting tea will work wonders, and small plants (seedlings-clones) love it. The simple recipe is 1 TBS/gal of EWC, and 1 tsp/gal of a sugar source, ( I use Humboldt Honey, black strap molasses will work also.) I brew it in a bucket with an air stone for 24-48 hours. I apply this tea directly to my clones and seedlings, they love the shit out of it (literally.) I also add it to my nutrient mix @ 1 cup/gal as a microherd boost. I use whatever I need over 2 days and then dump it and start over. It is really cheap to make. A small bag (15lbs.) of EWC will last you forever doing this. If you want to get fancy you can start adding other stuff in to your tea. As someone on here I believe it was Malignant in his tea thread or someone he was quoting, each tea is unique to each individual and their needs and applications. But remember K.I.S.S., keep it simple, stupid.
Here is my normal tea I brew ever 1-2 days. I mix 3-5 gals at a time, but here it is per gallon. It provides good nutriton for seedlings and clones, and keeps your soil active.
-1 gal water
-1ml Floralicious +
-1 TBS EWC: I use wiggle worm
-1/2-1 TBS Earth Syrup: (good stuff, an all around good supplement source and tea maker, acts as food source for microbes also while giving a little more nutrition to the plants. The EWC and Earth Syrup work well together. The EWC provides microherd and light nutes, and the Earth Syrup is a molasses based compost activator and light nute source so it is the food source for the EWC microbes.
-1 tsp Azomite: (optional, just add it to bolster my trace content since I don't reapply azomite throughout my grow
-Stir vigorously to break up the EWC and Earth Syrup powder clumps until it looks uniform, then just let it brew for 24-48 hrs. I use it after a day of brewing and whatever I don't use will get used the next day. After that, I empty my bucket and clean it and my airstone thoroughly, it gets pretty gunky. Wash, rinse, repeat.

NOW! That all being said. My relationship with BioCanna is a love and hate one. I hate the fact that I can't get a complete line of nutrients and supplements from Canna for what I find lacking in their nutes, and their customer service is attrocious. Ralph B. (Canna rep) is a joke. They tell you not to use a soilless mix and to use a complete organic soil blend like Ocean Forest or Happy Frog. I have used both, and in the end I had to start adding my normal nute regimen like I do in my soilless set up. Maybe if I used bigger buckets this would be different, but I ended up just going back to my simple Pro-Mix blend as I like the consistency and drainage of Pro-Mix better than any other soil or soilless I've used. (Ocean Forest, Happy Frog, Advanced Sunshine Mix #4, Coco, Roots Organic, and some others I can't remember. Use the Pro-Mix Bx if you are considering using Pro-Mix, it is almost all organic and has mycorhizzae added to it to help bolster your microbe colony. The reason that I keep using it and haven't switched is because i get a really nice finished product and great resin production. Yields are a bit lower, but the quality is phenomenal.
I water every 3-5 days and they normally get about 2.5-4 quarts each time depending on pot size.
A typical feeding in veg looks like: 1ml Roots Excelurator, 1ml Floralicious +, 2.5ml Dark Energy, 15ml BioVega
A typical feeding early flower feeding is about the same, just add in Flores. I switch from BioVega to BioFlores at around day 10-14 of flower, depending on bud development.
Weeks 4-6 (Bulking time) I do 1ml Floralicious +, 2.5ml Dark Energy, 4ml Nature's Nectar Nitrogen, 15ml Budswell, 15ml BioBoost, and 30ml BioFlores.
So ya, that is basically the bulk of the information that I have gathered over the last couple years using BioCanna. I hope it helps. If you have any other questions, feel free to ask.
And then, when you get some confidence just plant another seed or clone right in that same soil instead of throwing it out and be surprised !!
