Hey All, I am growing girl scout cookie extreme in fox farm ocean soil. I was wondering what people use as an indicator it is time to start feeding ?
You want to keep an eye on your runoff ppm’s and when they get low you’ll want to start feeding. I usually get 4 to 6 weeks out of ocean forest
I’ve been told to start when TDS readings hit 800/1000 on runoff. Be careful as I fed too early and had an issue. Didn’t kill her just had to flush and deplete soil.
I grow in OF my runoff ppm’s stayed high through six weeks of veg. Within a week after flipping my runoff readings started dropping fast. If you’re not taking ppm readings you should start.
What ppm meter do you use ?
Missiles is spot on. With brand new FFOF 4 to 6 weeks. Some say 8 weeks.
