I have had a small sprout of lemon tree (Eureka lemon, if I trust the label) for a few months, and for the past two it has been looking weak and sick.

In particular, it's not making new leaves (although it did grow a little) and the three existing ones appear sick and dry, with spots on them (see picture). At first, there was also some web-looking white fluff on them, although it seems to have stopped (for a while, I assumed a spider was building its web on the sprout).

I have tried using water enriched with nutrients (this one) for the past month, but it did not seem to improve.

What should I do — any idea?

I can try to get better photos if these ones are of too poor quality: my cellphone is sort of a shame in that regard.

It looks in your photos as if you have it in a small cup with no drainage. I would surmise from that & the condition of the leaves that it is over-watered and probably suffering from root rot.

Replant it into a container with drainage holes with a rich, well draining potting soil. Keep the soil damp but not soggy and give it some time.

The dark green veins and light green leaf material also indicate an Iron/Manganese deficiency which is very common with citrus grown on alkaline soils.

See here for more detail. Repotting with new soil, more light, more drainage and a touch of acid or citrus fertilizer should fix all the symptoms.
