is new growth on plants generally lighter in color?

It can be depends on the plant you have or it could be a iron deficiancy.

hairgrass and riccia.

 

[trenac]

These plants should not have lighter new growth, how is the new growth on the other plants?

 

[turtlehead]

same maybe it's my driftwood leeching tannins.

 

[trenac]

I don't think tannins would make your plant leafs appear light in color.

Have you just planted these two plants?
