Newly hydrosseded and Old existing Fertilizing Schedule?

[haventhrows]

Was wondering if anyone had a good recommendation for a weed/fertilizer application schedule. Recently cleared and hydroseeded my backyard which was over grown with weeds, wildberries, brush etc... The grass is coming in well except for a fews small spots that get excessive water from run off after storms and have a (cotton, spider-like) fungus killing them. I would like to get the new lawn on a weed killing and fertilizing schedule as well as the front lawn which isnt in the best shape, mix of weeds and grass when looking up close. Any recommendations for fertilizing and weed prevention? I want to be careful and not damage the new lawn because it is coming in well. According to most professionals, you should fertilize after the first or second mowing. I just mowed the new lawn yesterday and was looking to fertilize. Thank You in advance!
