I have used earth juice,foxfarm,advanced and many others---there are a lot of diff feeding schedules that will get you to the same place--the plants can handle the nutr in full doses but you have to start low and work your way up the ppm ladder(1/4 every other feed,plain water then the next time1/2 and ect.). as the plant and roots get trained by you they can use more nuts---they will talk to you and tell you when its time to back off a little or add more. You should have a baseline to start like---------ph6.3----week 1 and 2 plain water. week 3, 250-400ppm then increase ppm's each week by 50 to 100ppms. good luck
