Environment

Slow growth

The plant just isn't moving. Work through the basics: pH, EC, watering, climate and light, then the roots.

Symptoms

  • Little or no new growth over a week or more.
  • Small leaves and short shoots.
  • Often with pale colour or other mild symptoms.

Quick checks

How to fix it

  1. 1
    Check

    Run through the basics

    Check the basics first: feed and run-off pH (5.5–6.5), EC for this week, watering, climate and light.

  2. 2
    Environment

    Warm and water correctly

    Keep nights above 15 °C and water by weight.

  3. 3
    Feed

    Feed to the chart

    Start low in each range and move up as the plant responds.

  4. 4
    Physical

    Check the roots

    White and firm is healthy; brown or root-bound needs action.

  5. 5
    Support

    Support roots and vigour

    Root Shoot is designed to build root mass; Monkey Mist, in growth and early flower, can give a quick boost.

Likely causes

  • Cold roots or cold nights.
  • Over-watering.
  • Feed too weak, or pH out of range.
  • Weak light.
  • Root problems (rot, root aphids, root-bound containers).
  • Recent transplant shock.

What to avoid

  • Don't change several things at once.
  • Don't overfeed to force growth.

Prevention

  • A grow diary with weekly readings.
  • Container sized to the plant.
