i actually just made a couple phonecalls around my area to see if i could find a decent fert for my plants. I found one thats for tomatoes and the percentage is 18-18-21 n thats the closest they have to 20-20-20. So im gonna go pick that up tomorrow, and im gonna let my plants dry out, water them , let them dry out again, and then ill use my new nutes. Thats what i should do as far as letting the nutes i have in there already run their course before i introduce something different into the soil right?
