When should I trim. 4 week old plant about 12 inches hi. Good top leaves, about 3 sets. what are the 2 lower round leaves and 2 single leaves at bottom. Should I cut them.
do not cut anything, if fan leaves get in the way, bend them so more light hits the plant but do not cut anything (unless you are topping or doing it for a reason)
The two round leaves at the bottom are the starter leaves.. They will die off soon.. My Journal - 2 x 150w HPS Closet
