Plant diagnosis

I wonder if some one would be kind enough to
look at this plant:

www.ibrox.freeserve.co.uk/images/hygro.gif

It's a fast growing plant (I think a Hygro of sorts)
and looks to have some kind of deficiency. Searching
the web I think it may be Potassium. Can anybody
confirm?

Many thanks

However, a certain degree of soil nutrient availability is not the only factor affecting its absorption by plants. Other factors, such as temperature, humidity, soil moisture, plant diseases, etc., greatly affect the absorption of nutrients. Therefore, the analysis reflects the effectiveness of plant nutrients in soil and plant nutrition.
