Get the Mixture Right.

My tomato plants have just not been experiencing the kind of growth that I had expected due to the fact that I misunderstood how to mix the grow solution. I bought two mixes one is mix A which I thought was for flowering plants and the other was mix B which I thought was for leafy plants. Visiting the HortiShop this morning confirmed that equal parts of BOTH solutions needed to be added per liter, only providing mix A will result in poor growth and yellow leaves as can be seen in my photos. Mix A and mix B can not be mixed together in their powder form because they react with one another.
