Plant Magic Old Timer Organic PK 4-8

An organic PK lift for the final stretch of flower

Plant Magic Old Timer Organic PK 4-8 is an organic flowering booster that raises phosphorus and potassium through the critical late bloom stage. Built to run alongside Old Timer Grow and Old Timer Bloom, it delivers PK in an organic form that feeds heavy flowering while keeping microbial activity in the root zone healthy. Late in flower plants demand more P and K for energy transfer and flower formation, and without it buds turn airy and yields drop.

Key Benefits

• Organic PK booster designed for the bloom stage
• Extra phosphorus and potassium for stronger, denser flowering
• Improved bud density and higher overall yields
• Late-flower uptake supported when plants need PK most
• Range compatibility with Old Timer Grow and Old Timer Bloom
• Organic and soil-suited, ideal for organic indoor growing
