That picture link is for you. It doesn't work for us. Just upload the pic here.

Sorry about that, I changed the settings so it should be fine now, however I've attached the images here - unfortunately they are slightly...big.

And the other one. Do forgive me if there is a way to upload both into 1 post, I cannot seem to find that option.

The little spots could be aphids or whiteflies (ick!). I would spray with insecticidal soap.

The dead area doesn't appear to be an issue. It could be physical damage. Otherwise the leaves look nice and healthy, though it's tough to tell the color.

What soil are they in? Have you been using any fertilizer? If so, how?

I've been using compost that I brought from a supermarket, it's been totally fine with my other plants, no fertilizers yet.

That said, to my eyes the leaves are still loosing their colour and the dead bits is growing more. Any advice on that?

Darkfall,

First, welcome to the Forum. We're a generally friendly bunch who rarely bite ;-)

Based on the last photo posted it looks like marginal necrosis to me. There are numerous causes most usually related to a nutrient imbalance / deficiency but in your case it may be related to your water.

Are you using tap water to water the plant and if so, do you have high levels of fluoride in your area? The chlorosis extending from the veins and necrotic areas around the edges seem to point to fluoride toxicity.

From the Arizona Co-operative document linked below:

4. Foliar marginal necrosis is the most common symptom of fluoride toxicity along with Chlorosis along and between the veins occurs in fluorine-sensitive plants. With many plants, the marginal necrosis is preceded by the appearance of gray or light-green, water-soaked lesions which later turn tan or reddish-brown. Injury generally occurs at the tips of the leaves first, then moves inward and downward until a large part of the leaf is affected... fluoride excess

You're closest to your plant so have a read through the document and see if any other descriptions better describe the symptoms your plant is exhibiting.

If it was me, I'd hedge my bets and a) flush the potting medium with distilled water; b) give it a light feeding with a general purpose fertilizer that includes micro nutrients and; c) continue using distilled water for this plant until it recuperates.
