Think I missed the first question, glad you found good answers :o)

Hi Pip c (wow - beautiful Siamese).......absolutely love siamese cats, had a lilac point myself!! I would appreciate your take on the problem - more answers make my life a lot easier!! Have tried the fertilizer, but do you have a different idea??

Don't really have anything to add to what Dorjac said, sorry, lots of mineral deficiancys cause leaf problems. Magnesium...sulpher...iron....nitrogen you name it :o(
She really is a beautiful cat! She's not mine, a friend's, we can't have cats cos Mum's allergic, but I love them anyway

Thanks Pip c.... will keep on with the fertilising!!!
