alright so this is not my first time growing but i am totally confused on this one. i calibrated my hanna digital ph meter with the 7 and 4 solution. i have 10 seedlings 2 1/2 weeks in to life and when i put my meter in the soil its reading me crazy numbers like 1.70 then jumps to 3.20 then drops back down and the ph symbol goes on and off. i then wash it and take it out and place it in the 7.0 solution and it reads the 7. is my soil very low?? i am using MG organic soil? could it be the soil i am using or my meter is retarded.......
