Is the MSU repotme liquid orchid fertilizer safe?

[Plantcrazed101]

Hi y'all,

I have been wanting to experiment with my fertilizer a bit, since I've only been using 20-20-20 fertilizer and my violets have been showing signs of PH that is too high despite regular repotting. My orchids don't get fertilized as much, but I imagine they may be suffering too. So I went online and found MSU fertilizer in liquid form on RepotMe, and ordered some.

I'm really worried though!!! I read all these horror stories and then found out that MSU isn't actually the one making the fertilizer? So should I just return this liquid fertilizer? I really don't want to kill my plants or have fertilizer that never ends up getting used because there is only one plant that likes it :/ What do I do?
