I have 32 small and rooted clones that are about 8" tall some bigger some smaller but they are not growing. There are thin white roots coming from the bottom of the cube and going into my current culture system but after a week in there they have not gotten any bigger. I had a problem with my last run so I disassembled it, cleaned everything, bought all new irrigation and air line and started using current culture nutrient line. Before I was having no problems with heavy 16. The reason why I switched is because I think heavy 16 somehow caused the system to become contaminated. Any suggestions if that could be it or what I should do or if I'm missing something ?
