The basic requirements of growing cannabis include light, nutrients, water and an ideal grow environment. In marijuana cultivation, providing the plants with just the basics is not enough because growing cannabis entails great responsibility, effort, time, money and some skills to obtain abundant harvest of quality and potent buds. Knowing what are the common problems that can affect or slow down the growth of weed plants can do a lot of help. Determine what the causes of stunted cannabis growth are and know how you can prevent them, so you can be assured of growing healthy marijuana crops.
Common problems in growing cannabis that can slow down growth and ways to correct them:
Inappropriate spectrum of light
Light is one of the basic requirements in growing cannabis, whether you decide to have it in a greenhouse set-up, indoors or outdoors. It is very important that marijuana plants are able to receive the right amount and spectrum of light most especially during the vegging period and budding time. Failure of supplying the weed plants with the right light spectrum can cause stunted growth. Cannabis plants need the blue spectrum during the vegetative phase while on the flowering period, the plants need the red spectrum of light.
Too much water can hurt the marijuana plants. It can suffocate the roots and prevent enough oxygen uptake of the roots which will eventually lead to root rot and slowing of the plants’ growth. Watering the ganja plants can be done twice daily or depending on the level of temperature and humidity of the grow room.
pH of the medium used
pH of the medium that is too low or too high can cause underdeveloped marijuana plants. Acidity of medium will make the plants unable to absorb nutrients. Thus, resulting to an inhibited growth. The pH required may vary with the medium used. For soil medium, make sure that pH is at 6.5 to 7 while aeroponics and hydroponic growing medium should have a pH of 5.5 to 5.8.
Low nutrient strength
Weed plants receiving inadequate amount of nutrients are not able to sustain high growth rates especially during the fast vegetative period. Feed the plants with the right amount and kind of micro and macro-nutrients based on their needs during the initial stage of growth (seedling stage) up to the vegetative phase and budding time.
Discoloration of the leaves, drying, wilting and presence of blotches are just some of the most common implications that marijuana plants are unhealthy. Stress on the cannabis plants and stunted growth caused by overwatering, inappropriate light spectrum, low nutrient supply, overfeeding and acidity of the medium can lead to lower yield. Be acquainted with the different causes of stunted cannabis growth and correct them as early as possible to produce healthy ganja plants with massive yield.
