Hello! I will start to say sorry about my bad english, I hope you understand what I mean anyway. I have a question about a small hibiscus I have (by small I mean about 10 cm). It is cultivated from seed and have gone through a tough period with vermin infestation at a young age, looked to be dying for a while but has since extermination of vermin grown new leaves. (It has been pest-free as far as I can see in 3-4 months). However, as will the new leaves discoloration right quickly. (They turn brown closest to the "vein network"). It may have lack of something? (It stands in support lighting because I live in Sweden so it is not much sun in the winter). Do you know what it can be? Thanks in advance. (Does the picture open?) Sincerely Josefin

Hibiscus are heavy feeders, especially when forming buds and blooming.
I would use a balanced fertilizer, diluted in half once a week.
Give the plant as much light as possible, even using a grow light would be beneficial for a sun loving Hibiscus.
