hey guys I am not liking the way my plants are growing using the recipe with the base Floranova..
I am getting into week 3 of veg and start seeing deficiencies where there shouldn't be any. its been couple months trying to figure it out that I am sick of it. I have switched to canna because I vaguely used it once ( in rockwool ) and I was satisfied.
However, this time I am using coco. I use tap water which ppm is 100. One of my big questions about canna is whether I should use cal mag or not.. from what I have read in other threads, people are either for it or not, I know it also has to do with the cultivar and what it likes. in my case its og, and we all know ogs are picky little monsters
I also am seeing that people are doing fine with just a n b through the whole cycle, except some add pk boosters in flower. this already sounds a million times better than the last recipe I was using, and I'm hoping I don't have to go back after trying canna.
If you guys have experience and any inputs about canna coco it is greatly appreciated here , as this will basically be my first time using it.
thanks again in advance.

What kind of deficiencies are occurring? I don't use canna but Dynagro, and i do have to use a cal mag supplement to bring it all together. Around week 3 is i believe when it became very apparent that the cal mag was needed.

Hopefully others with actual canna experience will chime in as well.

I actually use only Dynagro FP and Cal Mag from start to finish in tap water. Doesn't get much simpler and it just plain works for me.

can you be clearer on what you mean with deficiencies? are you asking about coc or nutrients? Coco is inert regarding nutrients, unless you are asking about pre-charge? Canna comes precharged with calmag, ive never had any issues with just using straight from the bag, I recently switched to sanctuary soils coco since its premixed with perlite and lava rocks.

I ran a Fire OG cut in both canna coco and botanicare, in the same run, with RO water. Saw no differences from the coco, using House and Garden nutrients I only added calmag once a week because of the strain, otherwise I never run extra calmag

A&B

200 ppm in veg
400 ppm in bloom
cal/magic @120 +/- ppm

Veg to harvest

the rest of the canna program stays the same.

I only ever had a deficiency problem when I ran a light feeding schedule.

What type of deficiencies? Been using Floranova for years with no problems

I would start off with 0.4 EC of 50/50 Canna A+B and a high P/K flowering food (PK 13/14, Plagron Green Sensation of 0-9-10, or Atami B'Cuzz 0-20-30). Reason: the high P stimulates root growth for the seedling, and the high K creates a strong, healthy stem, to the point that you don't get purple stems or seedlings that need to be supported. With high K, gravity and wind only strengthen the stem, to where the plant grows faster because more nutrients and water make it to the foliage.

I would change that to 0.4 EC regular nutrients and 0.2 EC of the high P/K food in vegging, so you still have good root and stem development and a smooth transition into flowering.

At flowering, increase the P/K and magnesium.

Also, don't be afraid to use pure coco on top of a drainage layer of perlite or growrocks depending on plant size. Just water less often, and don't be afraid of letting it dry out - as long as you provide P/K for great root growth. Just look for wilting or nutrient deficiencies to show how much you can get away with.

Also, all dried media need to be hydrated before use. That includes worm castings, bagged soil and compost, and coco too. Just put coco in a tub of pH adjusted water for a day or so. Put perlite in a tub and add warm water until the perlite floats. About 10 minutes later, scoop up everything that floats, and disregard the rest. Put Growrocks in water and rince to get rid of the dust. Again let it sit in water for at least a day. Reason: If you don't, the medium will kill all the small roothairs and suck the moisture right out of any plant - which shows up as signs of underwatering - yellowing plants, poor nutrient uptake.

The high P/K, by increasing the root mass, eliminates the need for root stimulators. Also, because of the large root mass, nutrient concentrations can be much lower (EC 0.8 max on top of water EC) because much more nutrients are absorbed. This also pays off in the taste of the weed - much less chemical, and very pretty ash.

the plants I am growing are about 4 to 5 feet tall and 3-4 ft wide, around week 3 of flower I start noticing a lot of lower leaf dying off. it could be from not enough light hitting the foliage, but I have ran AN and plants are not affected.. I also feel like floranova since its so thick it can be very inconsistent, if it doesn't get shaken well enough... that being said, I wanted to switch to a more reliable and less muddy base

[GreaseGardens]

thank you all for your kind inputs , as to clarify I mean canna coco nuttrients , not the media..
so far, the plants have reacted positively to the switch and have started to see some new growth. using about 12-14 ml/g of a n b 3.5/g camg 5ml/g silica which equals out to around 750 ppm in week 4 veg.

thanks Tanzanian for the great info!
so to clarify a bit more , I want to add some pk booster in veg early? wat what ratio do you recommend? I usually add root excelurator in veg for a root stimulator.
