One of the problems with growing marijuana is the yellow leaf, this is a marijuana plant leaf that begins to turn yellow in color and this represents a problem.
This is a nutritional problem where the plant is being deprived of iron in most cases, which can be changed.One of the ways to ensure the marijuana hydro grown plant is getting the amount of iron that is needed is to use a fertilizer mixed with the water that is a 20-20-20. This means that it has all the nutrition the plants need to grow healthy and fully mature.
The way to know for certain if this is a problem beside the yellow leaves is to test the pH level of the nutrient solution often. That can catch the problem before it affects all the leaves on the marijuana plants that will usually begin on the lower leaves of the marijuana hydro plant.
