sounds like you have a lock out from the rockwool cubes ph. Do you soak your cubes in ph adjusted water or a rockwool pre soak before planting your seeds. Also you might have N def, try watering your soil with some alaskan fish emulison before planting in soil and i would spot using the rockwool cubes and try using peat pellets they are more forgiving and ph friendly.:rasta: :thumbsup:
