I am using emilys hydrofarm to grow my seelings in, they germinated just fine in a paper towel and began sprouting nicely in rockwool cubes once I put them into this hydropnics system. Its is now day 3 of week 2 and alot of my seedlings are begining to fall over on there side the frst one to do so is about 6 inches tall and the rest at 3-5 inches are following suite. I was afraid this may be because of the added floragro nutrients(3 bottle set) so i just changed the water to pure tap with no added nutrients. Any sudgestions? For light I am using an agrosun 150 wat dayspot clamp lamp along with the system being right under a winow.This is my first grow and its very sad/worrying to see this
