no problem man. If you set your first feed for an hour before lights come on e.g if your lights come on at four then you should set your first 15 minute feed for three o'clock. They take in a lot of nutrients at this time apparently. Then just set your other feeds at equal spacings during your lights on say a third of the way through your light cycle and then the other after another third. Then after about a week as they grow throw another feed in between those ones if you catch my drift. That's how I do it anyway but just find what works best for your plants. Just a case of giving them what they are asking you for. All the best mate.
