It's difficult to diagnose a problem without seeing it so we'll have to try to eliminate problems to try to determine the cause. Usually, overwatered turf turns yellow before it turns brown. This is because saturated soils can suffocate the roots, which shows up first as yellowing and then, when the roots die out, browning of the entire plant. Brown or burned patches sound more like water stress - not enough water - or sunscald, which can happen to young grass blades when the sun is very intense. A fungal disease can also cause the browning blades. Try looking at the affected grass with a magnifying glass. If you see black, brown or orange colored spots on the leaves, it's probably a fungal infection. Whatever the cause, you may simply want to rake out the affected areas and reseed. Cover the seed with a little compost or peat moss to help keep them moist so they'll sprout quickly.

Bahia turf can be fed in the spring. Use a complete fertilizer such as 16-4-8, in amounts as recommended on the fertilizer package. Best wishes with your lawn.
