I get the occasional yellow eventually dying leafs as well - yet the flowers are doing great.

My rule is just "grow through" your problems and eventually it all seems to sort itself out - me I would not overly worry about it - if you do a search you will find a guide telling you what each tell tale sign usually means - as long as your using your nutes properly and watching your ph- you'll be fine.
