I never did get round to mixing my own mate, mainly because I started using kelp in veg, which seems to offer much of the same benefits, such as increasing roots, vitamins , de stressing and a chunk of micro nutrients.
I just bought myself some RAW nutrient supplements after watching all the Harley Smith vids on youtube, which even though they are trying to sell a product are very educational at a base level. I picked up some yukka as a wetting agent, due to my coco been years old, some amino acids, humic acid and some microbes for flower.
Just wanted to try them out and get those chemical reactions increasing within the plant. One thing I noticed about their products is the feeding schedule, they increase P a lot in the first half in flower and then drop that right down in the second half while increasing the K. Which made me think about the canna line and any other line which has a PK booster like PK 13/14. Just seems that having both in increased amounts at the same time may not be as good as having the different ratio. Although I have to assume that the canna boost must contain a fair amount of P or the plants would be showing a deficiency early flower because you don't use the PK till later in flower. I have decided to add the PK earlier at the same time reduce the A and B to see how that works, still staying around the same E.C. Canna coco is NPK 5-4-3 which seems a lot of N for later in flower, not that ive ever seen N tox or close to it.
I may yet buy the RAW bloom powder and the P and K separately and try a run in flower with that to see how that works in comparison. All in a way to get one step closer to mixing my own salts, which I would love to do one day. Obviously I wouldn't buy RAW once mixing my own.
Ah Russell brand ey.. Nice one. Don't see him on TV much these days.
