to be honest with you , the size of your grow area needs to be alot bigger than what it is. now you have 4 big bud plants in hydro, i grew 1 bb plant in hydro and bent her 2 times, 1st time was at 4ft and the 2nd was at 6ft, when she was done she was over 7ft tall. now depending on your pheno type, with 4 plants growing at least 1 will out grow a 3x4 area. good luck
