There are 25 different ways to skin a cat, in other words, there is more than one way of doing it, same as growing plants. MJ is a weed, and will grow in many cases with or without your help. All they need is light and nutes. As long as they have those, they will thrive. 830ppm (for me) is a good 'start' for flowering and then raising it a bit later on into flowering. The plants will only take on what they need. PH is more imortant in very young plants and in starting seedlings, and becomes less important when they are older. In fact MANY nutrients actually adjust and stabilizethe PH so you don't have to worry about it once going into flowering. If you see your PPM go from 830 to 900 the next day, you know they are consuming more water than nutes. If the following day the PPM is lower, then you know consumption is more than you have been giving them.
