Athosanswered grow question 4 years ago There are several issues that could be contributing to the issue. First, dark green foliage and clawed leaves (tip pointing down) that's over feeding, in this case Nitrogen. Second; 0,4 liters of water per day is too much at this stage. The yellow tips, it is probably due a minor element lockout (again because of over feeding). 5 Gallon of soil does not need feeding yet, wait until the plant consumes the nutrients in the soil and shows the first signs of deficiencies, most probably you will not have to feed more than once or two times in the whole run.
