High, I have two seedlings on the go, and one of them is twice as tall as the other (it is about 2"). But the stem is fairly limp, and I can actually very easily bend it into a position, and it will stay there (this is how weak it is). Is this lack of water? I have John Innings No.2 compost which drains extremely quickly, and therefor, I mist it once a day. Why are my Seddlings' stems so weak???
