Thanks for the link and yes I think we have enough evidence that potassium was missing and the other day I was watching YouTube and a guy who specializes in plants said plants use potassium so much. That's why some guys even dose daily.Well, long before I got back in to the game a guy named Tobi Coring (founder of aquarebel fertilisers) had ADA soils tested at a lab in Germany.
So if these results are correct, I also have confirmation

That’s why ADA use Brighty K.
In the link Tobi recommends K is kept at 3ppm at all times. I calculated your dosing using Rotala butterfly and it would seem you are close to this assuming there is no build up. My thoughts are that if K was culprit then the plants are indeed using lots of K.
I notice when using EI things can turn sour after a while of good growth. It normally takes several 50% water changes using RO water to bring K levels to a readable level on my test kit (requires calibration) I don’t know if high K is the reason for poor growth but in terrestrial plants High K can interfere with both calcium and magnesium uptake. It’s amazing just how quickly K can accumulate dosing potassium phosphate and potassium nitrate.
I wouldn’t dose N or P unless plants are showing signs of deficiency.
Thanks. More evidence.I do run a high tech tank but potassium I have been dosing daily. No hygro left in tank now though and ferns have grown over swords (so can’t see any problems [emoji16]).

Hi Dela,
How much daily?
Hi Dela,
How much daily?
Any thoughts on the latest info on dosing levels? I never quite know what latest thinking is.
