potassium deficiency?

King Avitas · Oct 28, 2022

In living soil. About a month into veg. led lighting. Been feeding Bokashi Pro-Gro and Gaia Green 4-4-4.

Didn't think I was low on potassium already but this living soil stuff is new to me sooo.

What do you all think?

How often have you fed them and how much each time?

Just started feed them about a week ago. The soil was heavily amended when it was made. Giving them ¼ cup of each once a week.

Soil was built with:

Peat:
-7.5cu.ft. Sphagnum Peat Moss

Compost:
-1cu.ft. Sheep Manure Compost
-1cu.ft. Mushroom Manure Compost
-1cu.ft Sea Soil Fish Compost
-3cu.ft. Worm Castings

Aeration:
-4cu.ft. Coarse Perlite
-2cu.ft. Rice Hulls
1cu.ft Charged Bio-Char (not traditional airation but...)

Fertilizer Amendments:
10 Cup Kelp Meal
10 Cup Neem Cake

Mineral Amendments:
20 Cups Basalt Rock Dust
10 Cups Oyster Shell Flour
10 Cup Gypsum

I'm pretty sure it's a potassium deficiency but just wanted other opinions before I start blasting them with potassium.

You might consider a soil test. It could very well be lockout-I highly doubt you are deficient in K with that mix. You probably spent a lot to make that soil, a test will save you from adding more of something you don't need. Good luck!

Yeah, I was just in there putting the scrog net up and was thinking the same with all the purple on the stalks and stems.

Yeah, I might have to look into that. I have never done soil testing. I don't know where to start with testing. Ph testing is probably all I can do myself but that would be a good place to start I guess.
