I am currently growing 3 Girls Scout Cookies ans 2 Gelato's- all autoflowers. Im in week 3 of flower. I fed them today and the PPM run off was approx. 116 on 4 plants but 1 GSC was 759 (where it should be). I double checked the other 4 runoff PPM's and still 116ish. All plants look good with no issues. Any ideas?

Hello- Im in soil and I did not PPM the nut mix. Im using Fox farms nuts 1/2 str. I mixed 3 gallons, all the same and gave it equally among the plants.
What was the PPM of the nutrient mix going into the medium? Are you in soil or coco coir?
