I run about 15 strains a season, generally two of each. I'm always looking for the strains that perform well in the greenhouse environment I have at 49N. I love Angolese, but it won't finish properly here. Indoors you can control every aspect of the grow environment.
As previously mentioned genetics have the final say. Don't get caught up on a particular strain or name. Don't change a bunch of things you are doing either. Then you won't know what worked and what didn't.
Keep it simple, preparation is everything in growing great cannabis. I don't see a terrible overfeeding issue myself. I'm not a fan of synthetic anything when it comes to nutrients.
Neptune's fish and seaweed works great indoors or outdoors. Research the shit out of what you use(genetics, soils, Ph testing products and nutrients). I highly recommend Ace seeds...PM. Dubi or contact him through email. Let him know everything about your growing (tent size, Lights, containers and nutrients used). He will reccomend a strain for you and any changes you need to make. Your next season will blow you away! Peace
