Purple Leaves Phosphorus

Guavatone · July 9, 2019

These are German pinks with potato leaves. Can I get some help diagnosing.

I just Fertilized with Kellogg Kelp/Fish liquid last week and it didn't seem to do much.

The soil is a combo of Kellogg Organic soil bags with original container soil and peat, lime, worm castings, espoma garden fert, Dr Earth Tomato and Herbs fertilizer. I did a compost tea of the listed fertilizers a month ago.

Here's the pics. I already pruned one leaf that was much worse.

You're correct that it's a phosphorus deficiency and there's no need to remove the leaves.

Add some bone meal into the soil. Also make sure the soil isn't staying too wet which could interfere with phosphorous uptake.

Thanks a bunch! What do you think about Jobe’s?

Jobe's Organics Bone Meal Fertilizer, 4 lb https://www.amazon.com/dp/B003AZ4I3W..._L4qjDb7G6JSHW

Now i’m Thinking of DIY Bone Meal because I do bone broth all the time and have them frozen.
I wonder if I can get a decent phosphorus amount from chicken bones.

Phosphorous with some nitrogen deficiency. Root system is probably not developed. Let it dry well between waterings to stimulate its growth. Sounds like there's already lots of stuff in that soil, maybe too much not too little.

Microbiological fertilizers that contain nitrogen fixation and phosphorus mineralizer bacteria work well.

I’ve already used some of this:
