i cant edit my post. i did a lot of reading last night and i found out what the ppm does. are you supposed to start low and slowly move it up as the plant gets bigger?
I'm not sure why but you really think about feeding your plants more than anything else. If you want to feed your plants more, don't use Fox Farm Ocean Forest. There is plenty of food in there. The nutrient and grow shop industry has made you think that you need to add so many things or your plants just won't be right. Your soil has 1850 PPM of food in it already without adding anything at all. If you transplant every 2-3 weeks, you won't have to feed anything for 6 weeks. Your VEG nutrients are in your FFOF Soil. Your Bloom nutrients are also in your FFOF Soil. Every nutrient that you need to produce top of the line flowers are already in your FFOF Soil. I've been using this soil since 1999 and have never stopped. I love it. It's so easy as long as you don't think that you have to add nutrients. The only time that you will have to add nutrients is 2 weeks into Flower. Then you add nutrients every 2 weeks and you are all good. There are many forms of PPM meters and they all have different conversions for no good reason. So that means that 700PPM with my meter isn't the same as 700PPM with your meter. It varies by company and conversion that you use. No matter what conversion that you use, you would never go over 1400PPM or 2 EC.
This is a Chem4 x Sour Diesel in a 4 Gallon Pot of FFOF Soil which barely got fed anything the entire grow. There was over 4 ounces on this plant:
