Why Are My Cannabis Clones Wilting or Drooping?

Wilting clones almost always come down to one of four things: too much water, too little water, an environment that is too dry or too bright for the roots to keep up with, or shock from a recent move. Check how heavy the container is, how the stem feels and what the air is doing, and the answer is usually obvious within a minute.

This guide walks through each cause, how to tell them apart and what to do, plus how clone shock fits in. It assumes you are growing where it is legal and that you are 21 or older.

Why does a clone droop in the first place?

Leaves lose water all the time through tiny pores. Roots replace it. A young clone has a small root system, or none yet, so any shift in the balance shows up as droop first. The leaves go limp because they have less water than they are losing.

The job is to either reduce the loss or increase the supply, and to work out which side is broken.

Is it overwatering?

This is the usual suspect. Signs:

• The container feels heavy and the medium stays wet for days.
• Leaves droop but look swollen or glossy rather than dry.
• Lower leaves yellow and the stem base may look dark.
• A sour or swampy smell from the plug.

Roots need oxygen. Waterlogged medium has none, so roots stall and cannot drink, which looks exactly like thirst. The fix is to stop watering, move the plant to somewhere with airflow, and let the container get noticeably lighter before you water again. Water small amounts around the root ball rather than soaking the whole thing.

Is it underwatering?

Less common in a plug or cup, but easy in coco or in a fabric pot under a strong light.

• The container is very light.
• The medium pulls away from the sides or looks pale.
• Leaves are thin and papery and droop in a crisp, dry way.

Water slowly until a little runs out the bottom, and the plant should lift within an hour or two. If it does, the lesson is to water a little more often.

Is it humidity, heat or light?

A clone without a full root system relies on the air to slow its water loss. Droop in the first week usually points here.

• Dry air. Under about 50 percent humidity, leaves lose water faster than a small root zone can keep up. Use a dome and vent it daily, or add a humidifier.
• Heat. Warm roots are good, hot leaves are not. Keep the canopy under the high 70s, and check that a heat mat is not cooking the root zone.
• Strong light. A clone does not need much. Keep light gentle for the first week, as we describe in the first 14 days with a clone.
• Drafts. A fan blowing straight on a young clone dries the leaves. Move air around the plant, not at it.

Is it clone shock?

Shock is what happens when a clone is moved, jostled or has its conditions changed. A transplant tears a few roots, and for a couple of days the plant drinks less than it loses. A change in light, temperature or feed at the same time makes it worse.

Mild shock is a day or two of droop or paused growth. The fix is mostly patience: keep conditions steady, water only when the container is light, and do not change feed or light until it has pushed new growth. If you just moved the plant, our guide to transplanting rooted clones without shock covers how to avoid the problem the next time.

A clone that was just picked up and carried home may also sulk for a day or two after changes in light, temperature and humidity. Let it settle in a calm spot out of direct light.

Could it be roots, pests or disease?

If watering and the environment are right and the clone still droops after several days, check the plant itself.

1. Look at the roots. Slide the plug out. White and firm is healthy. Brown, slimy or smelly roots mean root rot.
2. Look at the stem base. A black, soft or pinched base means rot or damping off. A plant like that rarely recovers.
3. Check the leaves. Look at the undersides for webbing, specks or insects. Our guide to spotting a healthy clone shows what to look for.
4. Isolate it. If you see pests, separate the plant right away. The routine is in our guide on quarantining new clones.

How do I revive a drooping clone?

1. Check the weight of the container and fix water first.
2. Raise humidity if the air is dry, with a dome that is vented daily.
3. Lower the light so the plant is not working hard.
4. Keep the temperature around 72 to 77 degrees Fahrenheit.
5. Remove any dead leaves so they do not rot against the stem.
6. Wait. Do not feed, top or move it until it has stood back up and pushed new growth.

Most clones show improvement within one to three days once the cause is corrected.

How do I stop clones from drooping next time?

Start with a healthy plant. A strong, well-rooted clone handles the first week far better than a weak one. Water by weight, keep light and humidity gentle, and change only one thing at a time.
