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:

thanks u tink that my baby can make it or not?

yes it will make it just check your soil ph get around 7.0 to 6.8 and use the fish emulsion for N def it is more forgiving than a chemical fert. I also want to know what type of soil are you using.:rasta: :thumbsup:

Sounds like too much nutrients.I would lay off the nutes/It make take weeks to fix the problem but hang in there
