LED staying on very dimly

i have setup connect 2 seperate instances of led , photoresistor.
shine on photoresistor 1 ~3 sec, led 1 goes out.
shine on photoresistor 2 ~3 sec, led 2 goes out well.

you can put out led 2 if have first put out led 1.

only problem i"m having, after writing low led 1, there residual voltage keeping on. if shine laser on photoresistor 2 led dims more, not fully. when both leds written low dim.

i've measured through multimeter.
when led1 =  low, receives 0,27v
when led1 =  low , shine laser on photoresistor receives -0,03v
when led1 =  low & led2 = low receives 0,00v

/*  blind cyclops!
    het doel van dit spel om de photoresistor te raken met de laserstraal en zo de cycloop te verblinden. als de taak geslaagd dooft de led boven het hoofd van de cycloop.
    als het oog van de ene cycloop verblind kan er nog een tweede oog aan toegevoegd worden om de puzzel te vermoeilijken. daarbij kan bijvoorbeeld een specifieke tijd ingesteld
    worden waarbinnen de twee triggers af moeten gaan. de ogen van de cyclopen kunnen namelijk herstellen!

i suspect loop running faster imagine. both leds getting high @ beginning of every time loops. dimness looks steady merely alternating rapidly. dims further when more happens second stuff because ever prolongs low before high @ top of loop.
