Different fertilizers and stuff need help with a plan

[SHag42]

OK, Being the compulsive buyer that I can be at times. I have acquired more than I need for sure. Just every time I would read about something being good I would buy it to try. I would love to have some input on a plan to rotate these items I have or what would be the most beneficial use for them.
I have Miracle grow but decided to use it on my other plants after reading that orchids can't use urea.
So I bought
Better-gro orchid plus
Better-gro Better Bloom
Then for help with root growth I have bought
Superthrive
Seaweed
KLN

To much I know and keep seeing more things I want to try. But I need a plan to use them effectively. And not hurt my plants. It is my understanding that the KLN goes bad quicker so figure it is the one to use more often. But after reading about it on the label it worries me a bit with my pets. Oh and I also have Dip N Grow liquid rooting complex that more than likely I will just use on rooting's that I take from my house plants or shrubs. I know this is a mess that is why I need some ideas. I do understand that this is a personal preference and everyone has their own idea of what works. I just need some guide lines and then I can work on it from there. Thank you for your time and input.
