you know it wasnt in any paricular place it was the whole plant itself that looked like it was dying

you can buy a ph meter from a hydroshop hardware store or a garden place.... they are not to much...and are very handy... if its afeting the whole plant then i would have to see pics of the plant before i say anything... you didnt answer all my questions so i cant help much if you cant give me more details about your grow
