If you have a mature plant it could take 1500 ppm water, for the small ones less is better. My water is 380 from the well and I usually want to be approx 1200 for the plants. The runoff seems to be a little more generally. After a while, you need to clean and calibrate the ppm meter, it can start giving a low reading if it's dirty.

Be careful of over feeding your plant. If you listened to this advice and fed at 1500 ppm that's 3.0 EC, your plant would burn into a crisp. Your nutrient chart maxes out at 2.1 EC and that's at the end of flower.

Combine that with the fact that most charts suggest feed levels that are already high. Most people will start feeding at 50% or less of the nutrient chart suggestion. Good luck.

Why do you say that? mine take that all the time, not talking about seedling. I will alternate with plain water, but at 1500 ppm nothing here is crispy. I do agree about over feeding. I have only used the 1500 ppm measurement for the mature girls so why wouldn't my plants be burnt? Usually starting with plain water which is 380 from the well, 800 after they are a couple months old, ramping to 1500 max sometime before harvest in september, then plain water again in october.
