I'm using miracle grow potting soil that I found around the house.

Question - when should I start giving my plants nitrogen

right now it's about 9 inches tall and 3 weeks old, sorry I should have posted better pictures that showed it all, I definately will in a couple of days.

Thanks for all your help you've been a great help!
MasterBaker Reviewed by MasterBaker on . please help what does it mean if the leaves are turning really dark green/brown along tips of the bigger leaves on the top? This has only happened on a few of them but the discoloration disturbs me because i dont want to do anything wrong and if somethings wrong i want to fix it right away. The leaves on the bottom and under the big leaves on top are alright. Any help would be much appreciated. Thanks. MB Rating: 5
