OK so I did a little research and from what others have said, treat an AF strain much like you would a regular one. The only difference is that AF strains flower earlier and for a shorter amount of time so start bloom nutes as soon as they show sex. I havent seen anyone that recommends feeding more often than every other watering.
Most people were using FF nutes and said to stay away from Tiger. Also, keep in mind that the flower cycle is only about 5-7 weeks, so make sure that after about week 4 you are using only water no nutes.
A few have recommended sulfur (bone meal) in slightly higher amounts than a regular strain, like 2tbsp per gallon, or mix some into the soil. That should only be done after they show sex though.
As far as a "schedule" goes, it seems that very rarely can you define a set schedule for feeding plants. You want to just water when it looks like they need it, not when you think its time. And never use any more than the bottle calls for on any nute, most of the time start with about 1/2 the amount suggested and work your way up as with anything.
So in short, any nutes high in nitrogen & maybe some superthrive every other watering until they flower. After flowering go straight to bloom nutes every other watering. I have seen so many plants turn out amazing with few to no nutes at all, or even cheapo walmart stuff. Its always better to give them less than more, if they need more they will let you know. Remember just give your plant what it wants, not necessarily what you think it needs.
Hope that helps. If I find anymore good info Ill post away!
