Hi, I found a fertilizer especifically for hidroponic cultures that has a wide gama of chelated micronutrients and K2O, it's the only fertilizer rich in micronutrients I found here in my city, there goes the chart of the product...

Yara Vita - Rexolin CXK
Potassium Oxide - 12%
zinc chelated by EDTA - 4,2%
Fe chelated by EDTA - 3,4%
Mn chelated by EDTA - 3,2%
B - 1,5%
En - 1,5%
Mg - 1,2%
Copper chelated by EDTA - 0,5%
Mb - 0,05%

Now the question, ist it a good or a bad idea to use it in an planted tank?!?
Alone or together with KNO3, K2SO4 and KH2PO4?
Thanks in advance!
(P.S. Sorry for my terrible english!)
