that not all nutes come in 3 part formulas,I use the"GH" flora series(micro,grow,bloom) The flora series allows you to adjust the mixture for different phases of growth,but use the nutes that you have you've been using,since they are doing a nice job.What brand are you using anyway? Your grow looks fantastic!....bonbon
