So ive been having some issues with nutrient deficiencies so i started all new soil and went with coots mix. But the problems still persist. My ph is 5.5 in one 6.0 in another and the last is 6.5 but tbh i really think my ph pen is messed up. I have been feeding with dragonfly earth medicine teas. Also my soil is about a month old and did not really cook any. Now as for the deficiency i believe it is iron but not sure if i am correct that it is how would i fix it?
