So i got a bunch of TGA super soil (pre bagged) and so far im loving it. But they do have a bit of light lime green fade and some purple on the stems so i know they arnt 100% healthy. Im wondering what should i feed it to help them out? Im just feeding them nutral water with 0-10 PPM so they are on a straight RO water regiment. Any advice? I was thinking maybe a little CalMag but wanted to check with experianced super soil growers. Thanks guys have a dank day!
