I can't complain in general, but it is needed to mention two thing. The first is that for two plants in 15liter pots each I used very little of the fertilizers. So it would be better to have less volume bottles. 100ml or even less for such amateur growing. All fertilizers are very viscous so it was hard to measure the needed quantity. Another drawback is that they they don't dissolve very well in water.
