GhopZZ.... Autoflowering strains tend to need very little feeding as a rule. If you start them, in a good quality soil like Happy Frog or Natures Blend (both very mild nute wise), they will grow from breaking the surface to day 20 (the week they generally show sex) with no added ferts.
.
At day 20, I'd mix up my grow fert at 25 percent of the recommended mixing strength and water it in. Then 10 days later, I'd use my bloom fert, at 25 percent of the recommended mixing strength. Let ten more days go by and use the grow fert again at 25 percent of the recommended mixing strength. Let ten more days go by, and use the bloom fert at 1/2 the recommended mixing strength.
.
After that water only & let them coast to the finish line. The larger fan leaves will yellow and may fall off, but so what. That way you are sure, the extra ferts in the soil have been used up and the plant is stripping N from the fan leaves in order to finish. Plants without excess ferts in their tissues (smaller leaves/buds) smoke smoother and taste better.

Hope this helps....
