Are you talking about rooted clones or fresh cut clones, my rooted clones go right into veg with about 400PPM/0.7EC and always look great in about 2 days.clones should have nothing but plain water. i have a great schedule and recipe in my thread my 3 stages of flower.
I must have some messed up BB then....i can go to 2400 on some with no problems but they like 1000 better.
