A gardener wanted to know if E-Z fertiliser would be good for his vegetables. He fertilised all his bean plants with E-Z fertiliser but didn’t put any fertiliser on his pepper plants. His beans didn’t do well at all, but he got a good crop of peppers. He concluded that E-Z fertilizer was no good. What are the errors in this experiment? Tick all that apply: * A) Not enough subjects
B) Subjects were not similar
C) Conditions were not kept the same
D) The experiment was not reproduced

Pick more than one please :))
