Either increase R2 and R3 value or increase C1 & C2 value. You also did not tell or show how the LED are incorporated? I suggest you read up a little on how a transistorized multivibrator works.

Bipolar astable help
I has able to make a working astable with two 2N3904 transistors, two 100uF caps, two 1k resistors in the outer left and right, two 10k resistors in the inner left and right.

When I first tested it I saw that, when connected with two LEDs, that the two outputs switched back and forth a bit to fast for my liking so I tried to slow it down but I wasn't about to figure it out...
Can someone tell me how to do it, please??
