Hey ItsCannaDog,
I tihnk 1150 PPM (2,4 EC) is really high for 3 weeks of growing.
In my opinion it should be like 650-800 (1.3-1.6 EC).
To get higher PPM, i preff to add more basic nutrients and not additions..
But in your case i would lower your PPM.
1150PPM is only for flowering at mid-late stage.
Good luck
