i use canna coco and boost in coco coir and this is just my opinion and works well for me with no deficiencies...put all your feeds you need for the next watering and the correct amount of water in a big bucket mix well and leave over night. the salt should float to the top then give it a good mix again and the salt will settle at the bottom after a minute or 2. then ph your water then your ready to go but remember the whitish brown flakes are salt at the bottom so try not to get them in your second jar or bucket you use water plants
