Okay I'm Going to try to word this right. But it's probably going to be really confusing as I have not a clue as to what I'm talking about [emoji23][emoji23]
Okay so I have a low tech tank,no co2 high light I think - I don't have a par meter), I run the light for 6 hours, right now with my dosing of thrive and equilibrium these are my results per rotala butterfly, I have no idea what this turns into as far as npk.

My testing from home is as follows
Ammonia 0
Nitrite 0
Nitrate 30-35
PH 7.4-7.5
Phosphate is higher than my test kit reads so above 3.0
Kh 5
Gh 6.5
Tds 225
If I went pps-pro I wouldn't be able to get the npk that was recommended by ZxC so I need to go dry ferts I'm assuming from what you and ZxC are saying.
Which is 5 different things
Kno3, kh2po4, and k2so4 (optional), for micros its csm+b + iron chelate 11%
So I would have to figure out what amount of those to add to give me a npk value of what ZxC recommended 20-5-25, I know that all those add npk and I simply don't know how to calculate all of them together to get those numbers
