I was told by a local supply shop, I need to flush the soil on my six plants.
In door grow
Soil run off is at 7.8 pH
Possible cal/mag deficiency Plants are in 3 gallon fabric pots with Mother Earth coco/perlite mix.
Watering with R/O well water with 6.8 pH.
Bought some sledgehammer to hopefully get things back to where they need to be. Just need some advice on actually how to use it properly. Don’t want to make things worse than they already are. Any help is much appreciated.
