This is my first grow using canna coco and I've searched every bit of the forums. Some people say 5ml/gallon of A+B is perfect, and some say they use 10-15ml/Liter of A+B. That's quite a big difference, so what gives?
I'd say the 10-15ml/litre should read 10-15ml per 10 litres at a guess.
10-15ml/litre is 4 times what Canna recommend. (4ml/litre)
Either someone typed it wrong or you read it wrong.?
I have only been using coco and canna nutes for 2 weeks but have had very good results with using 10/ml per gallon of water. gallon to liter is like 1-4 ( 4 liters makes a gallon) so its like 2.5ml per liter. I have read alot and most people seem to find better success with lower nutes and frequent watering instead of feeding heavy. Makes sense to me and my plants are real happy now
