Best coco nutrients

I use the canna nutrient range . Highly recommend in Coco. I live in a soft water area 0.1 EC so have to add some calmag up to 0.3. Then I add my canna nutes . The canna boost they use is excellent stuff , but be warned your plants will stink ! But in a good way lol

And to add yes you can get away with that but I would recommend a pk type booster for weeks 4-6 depending on strain. Like canna pk13-14 or 7-11 etc.

I think you can’t go wrong with canna, house and garden and shogun nutrients. I have used all 3 and found the house and garden works better with reverse osmosis water while the canna and shogun work better in normal tap water (hard water). I think your better off concentrating on dialling in a perfect environment and providing efficient lighting over thinking too much on the brand of feed. Hope this helps👍
