Outdoor flowering fertz

Anyone have some suggestions on a good outdoor fertalizer?? It needs to be a chemical because I cant apply it too often.(too far away) I used Grotek monster bloom last year but it has no nitrogen and by the end of flowering all the leaves were yellow or brown and falling off thanks for the help !

the leaves are supposed to be yellow and faling off by harvest, makes it taste better without all the chloraphil "wet grass" taste. but if you cant get out there very often maybe try osmocote time release ferts, the kind in the pink bottle is for flowering, just apply once and forget about it.

vilmorin for outdoor grow & for flower plants

i just use bloom booster miracle grow like 5 bucks for a huge thing of it works great
