I dose dry chemicals and I believe that plants don't care a NO3:PO4 ratio if they are not limited in nutrients. So does it make sense if there (in the water column) PO4=1-2 ppm and 20-30 ppm of NO3? 30:1 or 20:2? Raft of variation as you can see and what? Plants stop the growth? Rely upon it they’re still alive and look pretty much superbly. Algae? Nope. Please correct me if I’m wrong.
In some cases I used to dose PPS-PRO solution. As far as you know this one is very low of nutrients mix. But in order to be successful with this approach I should adjust my CO2 concentration at 15 ppm level and tune the photoperiod according to PPS-PRO standard. To my mind JUST IN THIS SITUATION NO3:PO4 ratio may play the key role, not as for EI.
Also I don't quite understand why anybody needs to make DIY liquid NPK for EI method. EI works perfectly fine with dry powders as well and it’s more easily to dose.
