The plants have been in the same soil for about the last 30 days. We are using dry amendments Down to Earth 4-4-4. We recently transplanted into 5 gallon pots about 2 weeks ago adding a little bit of fresh medium at the bottom. The only other thing that we have changed is the iSpring 5 stage reverse osmosis system we added to replace Walmart RO water. We checked it with a TDS tester and the PPMs were about 10. City tap water had a ph of about 7 but strangely the reverse osmosis came in at 9 ph.
Any help would be greatly appreciated.
