You can lower the PH of the water with vinegar or vitamin C to 6.5-6.6. Is the soil water logged, can it breath and what is the PH. Find out what the soil you got locally has in it then add up all the nutrients to see if you have too much of something. Try a foliar spray of kelp extract to see if they perk up.
