it makes sense that the "filter" may even be removing trace amounts of some of the possibly benificial minerals that may have been needed, so i will switch back to the tap.

so galvanized nails can provide zinc, any other simple solutions such as that?

i have a hydro shop nearby if ther are any products you can suggest i use to provide that little extra bit of zinc, if it contains other benificial nutrients as well that would be nice.
try too take better picture of affected leaves you said there is white speckling on leaves or is it just the tips ? and a picture of the whole plant is always good
