i agree,just cause the plant is a month old there is no gimmick in the soil that say it depleted at one month,if you start in solo cup just say,roots come out the bottom,you trans plant,the soil very well might have a little use to it,but if you watering every day the nutes from the bag soil more than likely are depleted,so you up pot ,roots go to work and try to find the bottom again,so why water the whole pot,you leaching again,so roots find the bottom of that pot again and take off,by this time you should have a good roots system going,you decide you want to up pot one more time,all cool but how big in size from last pot are you watering?i suggest watering around the outside edge of the old pot for a few days to let them roots break out and run,so now your looking at 60 days in ocean,guess what im saying is every up pot brings new nutrients to the pot treat it that way,more times than not i dont even start to feed the plant until i flip to flower and only start 1/4 strength,last and most important is if you already know the problem why even come here to ask,@MIMedGrower just trying to help,catipillar knows his shit and you might should consider what he saying,anyway hope any this helps,may the force be with you and good luck
