Different type of leaves, any suggestions?

A question from a fellow grower:

I am have a few plants that are flowering, they have been for 14 days now but a different type of leaves are appearing , seen pictures were the call it Australian bastard , but up on till now the plant looked like normal plants, do u know what to do, don’t look anything like I’ve seen,

Well, I cannot really tell what you mean by different leaves.

One thing that I can definitely ascertain from the photos. These plants are way beyond week 2 of flower. They are mature, and approaching the finishing stage.

Please clarify what you mean. Plants look pretty good.
