I keep running into what I think is nutrient burn. I grow in Fox Farm Bush Doctor Coco Loco. I wait about a month before adding nutrients to my water. I start at 500-550 Ppm then a week later I up it to about 750-850 Ppm. I only add about 16 ounces of the nutrient mix then 16 ounces of water. All ph’d to 6.5-6.6. I’m thinking about topping my soil with Fox Farm Ocean Forest - 2 cups per gallon every 2 weeks starting at the end of week 3 of growth to try to make it easier to avoid the burn. Any thoughts?
Coco should be treated like hydroponics and watered between 5.8 and 5.9 pH. I usually feed my jacks at somewhere between 1050 and 1300 for hungry plants. When you add your feed mixture to the water You’re effectively cutting it in half.
Disclaimer! I’ve never used the Fox farms Coco loco. So if it has some type of soil component you’ll have to wait for somebody who knows that stuff
I agree. Jack’s in coco can be run full strength from seedling with no issues. What you are running is a dilute mix and the plant has responded with the leaf issues shown.
Full strength and add silica to your nutrient regimen.
I use coco loco often with Jacks 321. I start a feeding routine around week 4 after the seedling period. My average input PPMs are 800-850 and I PH in at 6.5. It’s a blend but the PH works best in a soil range
I think there is something wrong with the ph cause the plants stems are turning purple. I don’t know why my ph is so off when I make sure to ph every time I add water/feed. I just ordered some dolomite lime. So I should add 2 teaspoons of it to the top of my soil and water with ph water as usual?
I’m sure it’s nothing you’re doing wrong, more times than not soils come out of the bag at the wrong ph and needs to be adjusted before starting.
Even some of the Mother Earth coco I use and find very stable has came out of the bag at 5.2.
It’s not a (must) because your feeding and waterings will eventually correct the ph over time but starting from day one with the proper ph is always beneficial!
3-5 tsp per 5 gallons of medium, scratch it into the dry layer and water it in until some runoff! You’ll be a big difference in a few days!
Ps. Feed at full strength jacks.
Another thing that’s a very useful tool but a bit pricy is this bluelabs media ph meter.
It will very accurately tell you the ph of the soil and allow you to correct it and monitor it as time goes on.
I’ll add the lime and get it to the correct ph and test again in a week, if it hasn’t moved, chances are going to be pretty stable.
Check again before flower maybe once more in mid flower just to make sure all is well!
This is my (seedling) in the seedling tent, she’s 27 days old and just waiting for room in the big girl tent.
Ph of coco was 5.2, I adjusted to 6.1 and it’s hovering right at 6.0. She’s got a few burnt up leaves from some missed waterings but she don’t care.
Big girl in the flower tent is still holding steady at 6.1, it’s made life a lot easier I will say, it’s also allowed me to test these different soils and brands and see just how off they are out of the bag. Unfortunately…
