I am relativly new to this site,and I have some questions I need answered please.I am starting from seed for the first time as I have always used clones.The seeds germinated Ok and I put them in a soiless mix(sunshine#4).They popped through the soil ok,but its been almost 2 weeks now,and only 2 of the 8 I have,have 4-6 leaves,the other 6 seem to have stopped growing after the first set of true leaves came out,and are only 1 inch high.They look a healthy green color,but seem to have not grown at all for a week now.Is this normal?
