It is a good thing that most plants are resilient little life forms,
able to tolerate our mistakes, impatience, and "one size fits all" viewpoints.
As was wisely mentioned, proceed slowly and carefully, and realize that while you want your plants to grow, your plants want you to learn what you are doing regarding their care.
Simply wanting and relying on some simple instructions or quick opinions from others is not a real way of actually learning to effectively care for plants. It is a beginning perhaps, so please do realize the importance of developing a relationship with them, and learning from them.
This takes time and patience, something your plants desperately need from you, and something you CAN give them that is just as important as fertilizer!
Trying to find the "right" fertilizer (brand/type) is only a part of what we need to do, for as was pointed out, even the right fertilizer applied according to some simple "instructions" may still not give us the best results over time. We need to learn to watch our plants reaction, and to respond to their reactions to what we are doing to them!
Fertilizer
choice is not the only thing a responsible grower needs to do. It is a good start and a good question, but keep the rest of what was suggested in mind also!
If you understood nothing else that Av said, this statement alone seems most important to me:
"Regardless of what you choose, you should start slow and learn to "listen" to the plant".
I fear however, it is the one thing that most people will overlook the easiest!
It is common to want to somehow rush the plants growth and make our plants quickly grow and mature into the fantastic plants that we see some of the growers here have. The best way to make your plants grow faster is to change your perception of time, by having another hobby or something else to do to take your attention for a while! Time is flexible!
A cook who knew this once expressed this aspect of time as: "A watched pot never boils!"
Bottom line and in simple terms, The one of the things I suggest you all mix with your fertilizer when you use it, is patience!
Good luck all!
