Bio Flores - Canna Nute - PH?

Anyone use the Bio Flores 2-5-5 from Canna? If you do use it, does anyone know how much this usually effects ph? I am running with RO water so my ppm is 0 and ph is 6.5ish but i cannot get the ph after i add the Bio flores. Anyone with exp with it know the ph ish?

The canna terra flores Ive been using has consistently dropped the ph to around 4 ( I dont hAve an ec, ph or ppm meter but I use the chart on the bottle of the ph tester). Ive been adjusting to 6.0 in my soil grow but it seems to be locking out cal mag and iron. I have to raise it a little more. Im a complete rookie. This is my first grow.

I use the complete Bio Canna line, their nutes are have a ph of 6.5 they are also buffered so you don't need to PH your water when using Bio canna line...part of the reason why I like it so much, makes things much easier...so if your water is at 6.5 after adding Flores you should still be at 6.5...One thing I learned about Bio canna is that it helps to add in some humic acid to aid the plants in feeding across a wider PH range...I use the Boost also and I'm not sure if that has Humic acid or not...also very true about the cal mag issues, I use a little General Organics CalMg+ and that seemed to solve the issues I was having.
