    Outdoor grow: dying plant! Can it still be saved?

    7/15/19 Just took it out of the soil today. What should I do? Keep and try to save or throw away? It’s Gorilla Glue grown in Fox Farms Soil and about 3 months old. I just add regular water and the rest of my plants are doing good except this one. The heat in Riverside is crazy hot!
