spark plugs are wet

[ter-ep91]

wel i was checking my plugs today as car is gettin more and more reluctant to start and ive noticed that the first 2 sparks on the left side are wet and the other 2 are bone dry
does this mean theres piston damage??

injectors, sure they work in 2's aswell,

are they wet with fuel?? or oil, imagine it being full, if so, serious problem

could be a sticky injector in this case two
