those plants have several def. I would use the miracle grow,molasses and some epsom salt and if you have a wal-mart near by they sell some stuff called super thrive it's a all around vitamin like a vitamin pack you buy in the convience store ,has vitamin a,b,1 2 12 d e and alot of micro nutrients you may need loosening the soil at least the height that the plant is down use something thin for around the main stalk so you don't damage the ball root after you feed them dilut it some more and give them a foliage spray a well make sure it your in the sun though shake off the excess water so it won't magnify and burn your leaves and pray to the mj gods but I had one like that and bought it back to life real green
