systemic products and fertalizer interaction

[imgliniel]

Hey guys, I have a question, I had a pretty bad spider mite infestation in a group of my phals and after repeated treatment I seem to have vanquished them (yippy!). I want to continue using one of the systemic products as a precaution for awhile (it is the bayer advanced 3 in one systemic, for incescts mites and bacterial/fungal diseases). However, I was wondering if it will interact with my fertalizer? For the phals I use grow more 20 10 20. If I water and fertalize (the weakly weakly approach is what I normally use) then a couple days later spray with the systemic (roots included) will the two products interact and cause any problems?

Anyone know or have any experience with this?
