Has anyone on here ever used Iguana Juice Grow or Bloom? I'm just wondering if the ratios listed on the bottle are appropriate, as I've heard that other fertilizers recommend putting in too much on the bottle and I don't want to overfert/kill any plants. The Iguana Juice Grow is 3-1-3 and recommends 3.5 mL of fert per L of water. Is that right?
