OGgrowsanswered grow question 5 years ago looking at your diary it seems to me that the plant is blocked with the substrate soaked, the roots need to breathe to develop. The humidity of your grow is also low. in vegetative growth it should be 70% -80%, this will help your plant to have a more vigorous growth, on the other hand as autos plants should be planted in the final pot, they should not be transplanted and yours are in very pots small, so they will grow little. I think it is too early to be already giving growth fertilization, this can change the genetics of the plant. let the soil dry well between each watering and apply only root stimulator until the second pair of real leaves of the plant is born and forms well. good luck mate
