General hydroponics nutes, what's your ppm at during flower?

[SmokeyMcChokey]

I used to run my wonder woman at 1200 ppm. Not sure if it's necessary but they took it fine.

Follow The CHART

Never followed a feeding schedule, myself. Been making it up more or less as I go along, the plants give very few fucks.

I get burn at anything over 700 ppm so far. And the ppm rises allot so I drop it back to 500 or 600 I found.

yep, same for me. 1.0 EC is about what my girls can handle. I'm at almost 9000ft elevation which is my issue.

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.

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.

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.

My elevation is only 1224 ft

I’ve been running 1000 to 1100 without issue, obviously lots of flushing at end but if mine are healthy your are probably really healthy. Looks great man!

Always use RO water. And follow that chart and you will have success.

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...
