Canna/Bio Canna, GHE and B.A.C. all make wonderful products that I can thoroughly recommend.
These companies are well established and industry legends, not something that occurs by selling crap products.
You really don't need to feed your plant like some do with 10+ products mixed together, the brands I listed all make one bottle complete fertilizers that do not need Part A, Part B or Part C added to make them usable, they are just well balanced complete products that actually work and are easy for new growers to understand. They are all highly concentrated, meaning you need to use very little and one bottle will last a lot of grows and/or multiple plants. I have used them for years and the results are excellent.
Bio Canna make Bio Vega and Bio Flores, GHE make Flora Nova Grow and Flora Nova Bloom and BAC make Organic Grow and Organic Bloom.
I have a bottle of each and use them in rotation - that is, one time feed with Bio Vega, next time Flora Nova Grow then Organic Grow and then the same with the bloom nutrients. Sometimes I get creative and mix 2 or 3 together for a "witches brew" and feel this way, between the the 2 or 3 fertilizers, my plant is not missing out on anything. Remember though, if mixing 2 together, use only half strength of each or if using 3 together, use only one third strength of each. The only other thing I would recommend doing, is to give only half strength of any fertilizer and see how your plant responds. It is very easy to correct a slight under feeding, but very hard to rescue a burn and over fed plant! The only other things to maybe incorporate would be a P/K booster for use during flowering, a cal/mag supplement, especially if growing in coir, and if you are really keen, a fulvic or humic acid supplement and a seaweed extract for root health. If you are growing in actual soil like in your previous diaries, as opposed to using coir, I would also suggest 2 waterings with plain water then a feed with nutrients/fertilizers, this 2/1 ratio will prevent the fertilizer salts from building up in the soil and burning your plants.
Hope this helps,........
