okey i have Advanced Hydro nutes,my question is shall i use the full str that they recomend or i need to use half or so ? my clones are week and a half old. any ideas ?
If you ahve them in good soil you shouldn't need any nutes for at least a month, then like the previous poster said, less is better, start at half and see how it goes. Full strength is usually meant for full size plants.
