This is newly batched material... it darkens with age (this is normal 
and does not impact the product usefulness).

This is iron carbonate. Are you sure your KH is only 2? Maybe try 
another kit? The reason I ask is that we have only ever seen this 
when the KH was rather high (like up around 12). Or maybe your iron 
level is already quite high? Do you know what it is? Or, it could 
also possible be iron phosphate if your phosphate levels are 
unusually high. Do you know what your phosphate levels are?

In the end it isn't "bad" but you aren't getting the full benefit of 
the iron availability to the stems and leaves... the roots will get 
it, eventually.
