It has to be the plants. these are dutch passion seeds. And whats frustrating is that they started off so nice and now this. This is my first time buying seeds im sick of going to the clubs and buying strains that turn hermaphrodite. I figure you cant go wrong buying them. But im doing everything right. Sufficient lighting, soil, temp, co2, PH etc. Ive got it covered. But I havnt tested the run off. I'lltest when I water them next.
