Has anybody ever had problems with their soil becoming so compact that it becomes difficult for water to penetrate into the soil? I´m using BioBizz soil which was fanastic in the beginning. During vegetative stage I had explosive growth, but now I´m flowering and my plants have slowly been turning yellow. I thought maybe I was overwatering at first, but the other day I stuck my finger in the soil and I noticed two things: 1) I couldn´t stick my finger in the soil because it was so hard and compact. 2) After scratching the top layer of soil away, which by the way was moist, the soil underneath was bone dry!. Anybody ever had this problem? Any suggestions?
