Italian Ice?

I started all seeds in an organic rapid rooter. I have a mixed opinion about doing so. It grows and feeds seedlings without nutrients. Although, I added nutrients(11/20) to reservoir to aid in growth. I don’t use rock wool because of environmental concerns and toxicity to plants if not cleaned properly. I am growing 8 at a time due to undetermined sex. I placed all 8 rooter cubes inside the same reservoir for ease and lack of equipment. I made a slight error in measuring out nutrients(decimals are extremely important in the metric system lol) . Luckily enough I didn’t damage my seedlings. My PPM was extremely high (5000+ high what a waste).
