I think soil is more between 6-7.. I never go above 6.8.. My tap is all over the place. It has dropped almost a point in the last week. It was always around 8 or 8.5 and now it is at 7.5.. Kinda weird maybe because its winter?? You need to get to the store, at the least grab some fish emulsion. If you can afford it get some liquified kelp ( will help with stress and not so feeling good ). That should carry you through the veg. Save your pennies or hope you have been good this year and that Santa may bring you some supplies or cash for supplies.. Organics won't drop the PH to much, if you get some distilled water and add some fish emulsion and sea weed, it should put you right in the range. Hang in there and get some good food for the babies!
