My thoughts have been very mixed. For me that is partly because of the short lived success of EI dosing. You will get a response from most ferts but things seem to stagnate very quickly. Iíve been quite meticulous ensuring I have enough of everything and eventually things just seem to stop working. I donít think we are talking toxicity per se but perhaps some kind of interference. Iíve been speaking to a lot of different kinds of plant keepers and at the moment Iíve gone back to substrate fertilisation and decent fish, shrimp, snail stocking. Iím still trying to bring NPK down despite 3 x 50% RO
water changes. Thatís assuming the test kits are accurate which I have my reservations about.
From all the information Iíve accrued over the years potassium dosing shouldnít need to go far beyond 4ppm. Iím focusing on getting my N and P from the fish and fish food and calcium magnesium and other micros are below the plants. Things are looking up for me. EI I donít think Iím going to be using this again.
