Also choose a fertilizer that will not change pH a lot during and after uptake nutrients such as Scotts Peter Professional fertilizer 17-3-17, Jacks Professional 17-4-17. Both of these are use for pure water, with full macro and micronutrient. They are from well-known companies, reliable, cheap, homogenous mixture, and stable for a long time. You can use them in vitro as well as in green house for orchids, house hold and outside lants. Smile :)
