cannabis seed sprouted but stopped growing

Incorrect pH level of your nutrient solution is among the most common reasons for cannabis growing problems, including slow growth. The reason for this is that cannabis thrives only in a relatively small window of suitable pH values. If the pH is off, the plants are unable to take in nutrients, even if they are present.

If you’re growing outdoors, situate your plants in an area sheltered from strong winds and heavy rains, and use chicken wire and stakes to maintain support.

Insects may feed on the leaves, affecting a plant’s ability to retain water and transpire. Other pests may damage the roots or cause additional problems. Any time your plant is sick or infested with insects, it will spend most of its energy defending itself and recovering from damage, which will slow down growth.


Any type of stress on your cannabis plants, including many hours of exposure to direct sunlight without rest, can also halt or slow down growth. If you grow indoors and suspect light exposure to be the source of stress, decrease the intensity or move lamps further away from the canopy if possible. Know that seedlings are particularly sensitive to intense light! If you grow outdoors and you’re able to, move your plants into a spot where the light is diffused, such as around a shade tree.

Make sure to dial in the correct pH level depending on your growing method. If you grow in soil, make sure the pH level is from 6.5 to 7.0. If you grow in hydro, an optimal pH level is 5.6 to 5.8. For soilless grows, such as coco, a pH level of 6.0 to 6.3 is optimal.

Seedlings and young cannabis plants are especially vulnerable. Allow your seedlings to mature indoors for some weeks before setting them outside.

Exposing weed plants to irregular light hours can cause a hormone imbalance that confuses their internal clock. Your plants could flower prematurely, or they could revert back to the vegetative stage. If this happens, growth and yields will greatly suffer. For that reason, make sure to keep your light cycle consistent.

Are there advantages for the plant?

No problem at all. It’s all too familiar. What you did is what I teach to be mindful of not doing. Of course GOD showed me after letting me make a few mistakes . What you did was planted the seed first then watered it which sent it deeper and put pressure around it which causes the no show. Then I begin to wisen up. Now before I plant my seeds, I do the very first run off not heavy, but enough to see water drainage. Then I plant them a nickels hight deep. From the top of a nickel to the bottom is how deep i insert the seed. Also directly in the middle for a good strength lst. But thats what you did, the same thing I was doing and blew about 10 seeds before I figured it out. I hope this is helpful.


When you are growing on a large scale, floor space is a premium. I don’t have the time/space to waste on waiting. I can understand if you have a few plants that it would not be a problem, but not for something like my grow.

I usually don’t know if my time has been wasted until I smoke them! An unpopped seed would not really waste much of my time, all things considered.

Cotton balls, elementary school, textbook techniques all explain what went wrong.
