Phosphorus (P)

[Berryboom]

Any one was a idea how much dolomite lime I need to add to 20 l pot to bring the ph to 6.5?
And the better technique?

It should have dosage on the pack/box buddy...mine only says on flowerbeds etc so i just lob a handfull in when i mix my soil or pot on...u can dissolve a spoonfull in a jug of hot water&feed when its cooled down👍

Hydro and Soil less Mediums

Phosphorus gets locked out of Hydro and Soil less Mediums at ph levels of 6.0-8.5.
Phosphorus is absorbed best in Hydro and Soil less Mediums at ph levels of 4.0- 5.8. (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Phosphorus Deficiency.

I am using Coco and VermiCompost at 50/50 ratio. I believe this is soil less medium right?

Worm casting is effectively soil or a big part of healthy organic soil. On its own coco is soilless but with the vermicompost you're on your way to making a rich soil mix.

Soilless mediums have very little nutrient output which allows you to tailor the nutes you're feeding the plants. At least that's what I think it is.

Not sure if anyone will see this, is my plant showing signs?

How would we know? You've given no info or photos.

That looks more like a Mg problem. Best to ask in the infirmary.
