I used to run my wonder woman at 1200 ppm. Not sure if it's necessary but they took it fine.
All things being equal, if running balanced nutes etc...running up to about 1.0 ec is a solid rule of thumb target for established cannabis, seems to me. Then adjust accordingly. A little taper up then down at the beginning and end of a grow cycle, great victory.yep, same for me. 1.0 EC is about what my girls can handle. I'm at almost 9000ft elevation which is my issue.
I agree as I read that all along. Never burned any of my plants until flower though and it's when my plants get over the 650 or 700 range or anything higher.Just keep doing what you're doing. Everything's looking good so far, there was a guy in another thread who had his ppm's up to like 1200 and he got his plants in trouble. It is always better to have less than too much.
Who made that chart. I modified my Reservoir to much bigger and I think I should be using a lower concentration now. I have a 13 Gallon reservoir for plants that drink 2 gallons per day RDWC. What do you recommend...Always use RO water. And follow that chart and you will have success.
