Plants with issues.

I have multiple plants with problems right now.

all growing in an ebb/flow system on solid nutrients. (miracle grow)

I have a white widow with yellow and dry wilting tips; (Plant 3)
another that has some yellowing around the outer edges of older leaves. (Plant 2)
and a third that has spotted areas on bad leaves. (plant 1)

Sorry for the mis-arrangement.
