That is a bad ratio, but thanks for the report.
Good or bad inquiring minds want to know. 
Do you use the Diamond K solution grade gypsum?
Power SI is a bit overpriced if you ask me.
Check out this thread and you may be able to save some money.
This question may require a chemist for the proper answer.
But the short answer is water can only hold so much in solution so yes putting too many things in one solution can cause dilution issues but also cross talk type reactions.
Like 2 things can combine to become 1 complex thing and fall out of solution.
Silicon is know to do this, I would be careful how you mix this one.
This is a good choice for adding gypsum, less issues when you have a separate rez.
You don’t need the gypsum with every feed.
BTW @TopShelfTrees1
That small rez gypsum system was designed for use with coco.
Our own aspen at the lab has showed me how well that works.
This is real good advice and I think this one comes from our buddy Coastal at the Lab.
Aspen uses it but most of her tricks come from coastal.
You have to mix a certain way or it is super easy to cheese up things with SI.
