Hi Vito...
First thing I will say is soil is a pain in the arse... I don't like it as I like to check a reservoir for my PPM... Soil has other variables in it that I usually can't control, that's why I use hydroton....(Clayballs)... I use A DWC system, with a top feeder hose.. I have to do this as the roots haven't made it to the bottom pot where the water and airstone are...
My plants are fed for 15 minutes every hour... My DWC system is a 20 litre double pot system with an airstone in the bottom pot.. All pots are linked back to the reservoir...
So my system is using a little bit of all systems... I take the best from each kind of hydro set up and use it...
I love Canna and yes I do use the other nutrients EXCEPT Cannaboost... That stuff is overpriced shit... PK 13-14 will do the same job.. I know, I've tried it both ways...
Rhizotonic is fantastic stuff and I use Cannazym like a vitamin shot for my plants... I only use it when I think they need it... Just for a little help..
If you choose to use Canna, some strains will need a little extra help in its nutrient... I use Growth Technology Australia's Cal/Mag/Nit as a supplement to my Canna products... I only use this when I can see the chloroform fading from the plants (leaf yellowing and the veins really seem noticeable) or if I have tip burn, or I think they need a Nitrogen injection... It might sound a little confusing but seriously your plants will tell you what they need...
You don't have to foliar feed during flowering... In fact, its probably better if you don't... It creates excess moisture which can cause MOULD... That is something you should try to avoid at all costs... Add Rhizotonic once to your res after you've finished your cycle of PK 13-14... It works for me... I also use it for a couple of days during veg... I don't use these products everytime I water, I find I don't need to...
The secret with Canna, use your additives first( Rhizo, Cannazym, PK 13-14) to the strength on the bottle or a little less, then top up with your Vega or Flores A and B to reach your desired PPM.. I keep most strains at around 900 - 1000 PPM... Halve that when talking about starting new cuttings in veg then gradually increase...
pH is really important when using Canna as it likes it a little on the lower side... From 5.6 - 6.0...
I think that's everything...
I have another thread that starts from the very beginning...
