Measuring EC or follow the instructions?

I measure PPM for my plants, which can be converted to/from EC, and I've found that the AeroGarden schedule is often too much for things like lettuce, and too little for things like peppers...

If you read through the Gardens forums, you can find that a lot of members here use different amounts of nutrients compared to what AeroGarden recommends. Some people like the simpler one-approach-fits-all method, even if it doesn't maximize your results. But no matter which method you follow, I recommend starting out with no nutrients until germination, half-strength for the first period of growth (so they can become accustomed), and then going with your preferred strength from then on.
