should i trust a cheap soil test kit from the grow shop? its just one of those little rapitest ones where you mix the soil into distilled water then crack a small capsule into it and observe the color change. according to the chart mine is testing wayyyy high in N and pretty low in P and K. plants were pretty shocked when first introduced but thats because i didnt let the mix cook for very long... i think. after about 7-10 days recovery they all look great aside from the lower growth which seemed to just never really spring back to life after the shock.
