Feeding nutrients with high N:P:K ratios

Hi All,

I'm just going to start with growing autoflowers (Beginner grower). Unfortunately, the local nutrients have very high N:P:K ratios when compared with Gaia Green/Fox Farm etc as below,

All purpose

14:14:14

20:20:20 + TE

Growth stage (High N)

30:10:10+TE

16:11:10:2MgO:TE

12:11:18+3MgO:8S:TE

Flowering stage (High P and K)

06:30:30+TE

10:52:10+TE

11:11:18+TE

I want to avoid nutrient burn cos the soil contains a number of composts as well (Cow mannure, chicken mannure, vermicompost, coco peat, paddy seed husks - releases nitrogen to the soil after sometime)

What would be the best way to feed such nutrients with high N:P:K to the plants?

Thanks all for the help, stay lit! 😃

What brand soil are you using and what brand nutrients are you using? It's generally recommended to stay with the ratios that they recommend - just lower the dose if needed. If you go against the ratios, you could have too much of one nutrient and it can lock out other nutrients.

@colthot Yeah it's really hard to tell for you sure since we don't really know how much and the ratio of nutrients in your mix. You could get a soil test from Logan Labs and then you'd know what you have in your soil to begin with. I believe you can also pay them for consulting; translating what the soil report says and recommendations for what to add and when.
