Regarding the leaf on the upper right - is it possible there is some spider mite webbing? I cannot zoom in enough for a clear picture.

Physiological stresses typically have symptoms from the edges of the lead (the margins) and moving inwards whereas infectious diseases due to virus, bacteria, water mold or fungus have diseased areas radiating out from inoculum (i.e. where infection started). In your case it is clear the problem is beginning at the edges and you have yellowing leaves so I suspect they are not getting the correct nutrients.

As to what nutrients are lacking that is not possible to say. But as you say, it is in a small pot so one approach is to change the pot and add a good, balanced soil.

I think, The watermelon wants nutrients(compost or N,P,K,Mg).
If It was haven't these Nutrients, turned light green color.
Please give the watermelon that Nutrients of compost or N,P,K,Mg fertilizers into the soil
