I know of two pictorials/infographics, first from Zapins here http://www.aquaticplantcentral.com/forumapc/fertilizing/62876-plant-deficiency-picture-diagram.html and then by hariom here http://infographics.myaquacalc.com/
It's worth noting that Plantbrain explicitly dislikes these pictorials because they can steer hobbyists in the wrong direction during troubleshooting, and they're so effective in relaying a point that any misinformation becomes that much more of a problem. I think hariom does a good job of stating "CO2" a bagillion times in troubleshooting, but definitely see where Tom is coming from.
My advice is to pick up moderate to fast stems, and I would recommend Blyxa japonica, Rotala indica (this is also known as "Bonsai"), Rotala rotundifolia, and/or HM because they trim well and tend to get dense and bushy for your scape. More importantly, moderate to fast growing stem plants will show deficiencies pretty fast, will recover from mistakes pretty fast, and are just cool staple plants that are easy to acquire and share experiences with. This way, when you show pictures of, say, small or discolored R. rotundifolia leaves even as the leaf matures (older growth), most all of us will recognize it as NO3 deficiency or at least have some ideas to kick around.

Is it okay to make a solution of KNO3, KH2PO4, and K2SO4?
I'm dosing less KNO3 since I the bio load is high. To compensate for the loss of K in the KNO3 I was wondering if I can use K2SO4 within the same 500 Ml solution.
