Indoor grapevine leaves pale with red fringing

Please could you help? My 80-year-old vine is lacking verdant colour. The leaves are just starting and they always look pale and washed out with red fringing. Can I feed it something?

I would say your grape vine has a magnesium deficiency. You can verify this via the following article which shows a grape leaf with this deficiency:

The following article will give you suggestions on how to correct this deficiency. You might want to look into a foliar spray of Magnesium sulphate.
