That looks just like my old housemate from Yass, except he would be wearing a trench coat and his shitty bicycle would be black.Knickers you need to ride that thing back too.
Any pics skiz? I use nitrosol for veg too.
I usually wait until the cotyledon's turn yellow before feeding them nutes. If you do feed only 1/4 strength nutes then work your way up from there.how long should i leave it till i feed my seedlings btw?....last time i gave them a 1/4 strength Nitrosol solution after 2 weeks. The medium im using has no nutes in it though.
