Plants look like they are thinning out. Is this normal?

Hi all.

I have 4 amnesia in autos. Just about to go into week 7, but I've noticed since I've used my pk 13/14 for the last ten days I went to check on them and do a water change, although they look like they are starting to form buds, I've noticed they are starting to look a little thin and are losing the bushiness they've have over the past few weeks. Apart from that they look healthy apart from the odd leaf lower down dying off which is normal.

Any info on this would be great thanks

Without a pic it is very hard to know what you mean

I would guess they have stretched now and that's why they don't look that "bushy" anymore.
