bty soil or coco you want a slurry 0f at least 450 500 ppms 400 will manifest as a slight deff ( Fadeing clawing ) not very green plants low vigor ,and if your late to feed your gona see some problem in a few hours to a day depending on media. If you under samsung 301h or Bs and or high intensity cobs with 660nm and or uv with 680 far and deep reds (Emerson effect) or any double ended shit 400ppms is a very bad idea unless you keep your light way to high for good results .
