To try to answer your question, first Superthrive is an enhancer (supplement) and not a full NPK type of nutrient. I don't use anything but a week NPK in that stage like a 1-1-1 formula. First thing is to take your Ph & PPM reading and record it (you will not remember) Then you add your nutrients to reach your desired level of NPK mix. Then you record that PPM reading, subtract the starting PPM and you have your NPK number. Adjust the Ph and let it settle. Then you add your enhancers (supplements) to your formula. When you are looking for a PPM number it's normally refers to NPK fertilizer. The supplements people use very so don't get the nutrients mixed up or you may under feed your plants and that has problems too. It will give you false readings on the leaf and make you think you are overfeeding in one area when in fact you are underfeeding in other areas. The only real true way is to check the nutrient content inside the leaf using a Brix meter. Hardly anyone uses one, and I only use mine when there is a big problem or Iâ??m trying something new. I posted a chart somewhere that has the feeding formula for GH nutrients. If you canâ??t find it let me know and Iâ??ll post it again.
