decking spacing

last summer, i finished a deck using mahogany decking. I spaced the boards very close together since it was during the humid, hot months (july and august). Now im noticing that the spaces clog with debris and water takes a little longer to seep through. Mainly im wondering if the spacing will be a problem in the substructure. Will it rot? Is it a major problem that i did not use 1/4 in spacing?

No major problem. Your spacing still may open some as the wood ages even more. In the meantime, simply clean out the cracks with a screw driver a couple times a year. The sub-structure should be PT lumber - it will last 25 or thirty years.

one concern with slow draining:
check the flashing and repair any areas migght be vunerable to leaks. Mahogany spacing does not change much with age and with more water sitting longer on the deck, their is more risk of water finding weak spots in flashing...
