N.L. = Northern Lights?
Stalks look flimsy, then you have to watch to make sure they don't keel over. Put a fan on them and I use Miracle-Gro 24-8-16 while they are vegging. The breeze created by the fan tells the plant to build up the stem with the extra nutes in the M-G. This combo has worked well with Armaggedon and Power Skunk via G13 Labs.
Good Luck, BigSteve.
