Molybdenum Mo 0.05Nota:
give a spike of 200ppm P during 1st week of flowering 150ppm P = 660gm MKP/1000 lit air and going back to 60ppm and gradually increase to 85ppm Jika menggunakan bahan lain untuk micro spt penggunaan EDTA, kenalah kira balik berat bahan berdasarkan % kandunagn unsur, contoh Fe -Edta ada 13% Fe, jadi berat Fe-edta untuk stok = 6.8ppm/0.13 = 52mg. untuk stok 100 lit berat fe-edta = 52 x 100 x 100/1000 = 520gm.....Cara kira untu yang lain pun sama ...asalkan % bahan di ketahui
