Hi Edmund83, I find it much easier to buy a pre-mixed formula. For my hydroponic setups we mix our own but it is very easy to screw up and sometimes the source materials of each element can come in a form that do not do well together. Be careful! It's really easy to (hate to say it, but) kill your plants! Especially in a tank set-up. Many pre-mix ferts also contain micro-nutrients and minerals. Most of these elements are only necessary in tiny quantities. As a general program I use fish emulsion and seaweed (very high in micro-nutrients) on a regular basis (up to once a week as a foliar spray - only when no bright sunshine, like late afternoon) and on larger nursery stock I often use a fertilizer called "Osmacote" which is a time-release fert that lasts for 3 months at an application. (It comes in different formulations and different lengths of duration as well). I'd just recommend staying with a pre-mixed fertilizer unless you really know what you are doing (like have a degree in chemistry!)  Most good fertilizer shops also sell smaller bags (at higher prices), just look around a bit. See what some of the other forum members have to say about ferts too, I'm sure they can make some 'brand name' recommendations. |

Ya i agree with you. We must study and do it in practically carefully. If not the plant can easily killed by one of the element!  Apparently , i still will buy those fert that already mixed well. But , at the same i also interest study those element which needed by plant. Sometime it fun and enjoy to learn it . Of course, one thing bad is time consuming. |
