Hi everyone. I am growing White Beelze Bubba by Karma in an organic soil mix. I am at day 35 of flower. The lower leaves are showing a clear phosphorus deficiency.
This picture is not from me but it looks exactly like this:
The soil mix has always had an abundance of nitrogen for this particular plant as evidenced by slight clawing / downward taco'ing of some leaves and a very deep green colour to the foliage. Nothing I can do about that this late in flower as I am, and have from the beginning, only feeding plain water.
My question is, can too much N lock out P? Or could it be that my soil is simply deficient in this element, despite being heavy on the N?
My mix is:
2 parts Seagreens Premium Organic Potting Mix

1 part Gardener's Friend Organic Compost

1 part perlite
Then I amended with:
1 Tb Blood and Bone per gallon
2 Tb Dolomite lime per gallon
My long term goal is to get rid of the perlite and build a soil that I can recycle, adding in what I need to after each run and letting it cool for a while.
I thought the compost I added in would have enough P, but it may not.
But in this case I am wondering, should I top dress with chicken manure to correct the Phosphorus deficiency? Or use a bloom fertilizer with a higher ratio of Phosphorus?
Any help would be appreciated. This is a long term focus for me as I started in Coco hempys and peat/perlite with synthetic nutes. I am committed to going organic but sometimes it's discouraging when this sort of thing happens. All part of learning though I guess.
