ALso, how many weeks to wait before using fert? I used fert on the second decent one and it completely went the other way and died. I only used 1/2 the lowest recommended starting concentration too. DAMMIT!!
If you're using "expensive" soil, it may already have nutes in it. I'm using Fox Farms Ocean Forest and I can easily go 30-45 days vegging with no additional ferts. That tells me that adding even half the recommended dose could od sensitive seedlings on nitrogen. I usually start with no more than one quarter the recommended dose, and haven't had to add anything to seedlings or newly rooted clones.
