[Support request] Early finish

Just finished my 3rd run with autopots, I’m having an issue where my plants are finishing too early I’ve run 3 different strains all of which I’ve run before and know to be 60-65 day finishers. In all 3 runs my plants are finished around day 47, the weed is good and cultivar expression is there but being 2 weeks early the yield is lacking. Any help or suggestions would be greatly appreciated I’m at a complete loss as to what could be the issue.. also I’ve got a friend with autopots and he’s also had this same issue run after run. He’s using Remo and I’m running floraflex
