Biomin Calcium

Symptom: Plants deficient in calcium first show stunted growth in new leaves and roots. Young leaves may appear distorted, yellowish, and develop spots or irregular leaf margins. Several vegetable disorders originate from calcium deficiencies. Blossom-end rot afflicts tomatoes and peppers, and the blossom end of the fruit develops a leathery, rotten-looking patch. Calcium deficiencies also cause blackheart in celery, cavity spot in carrots, and internal tip burn in cabbage.

If you observe these signs in your plants, you may need to provide more calcium.  Calcium deficiencies tend to appear on newer growth, which means it first appears on the leaves towards the top of the plant.

Some of the most noticeable signs of a calcium deficiency will appear on new, upper leaves which may display:

  • Dead spots
  • Crinkling
  • Spotting / Mottling
  • Small brown spots
  • Stunted growth
  • Small or distorted new leaves
  • Curled tips
  • Leaf die-off
  • Affected leaves may appear dark green
