Hello Buddhamel here. I have a question, I have four plants of northern lights special growing in seven gallons smart pots. Using advance Nurtients and 600 watts hps in a 4x4x7 tent. a couple of my plants have grew past my light and reflector. Do I cut down the tops of my plants. Which is into the 3rd week of blooming. Or do I leave them be. I veg the plants close to three weeks before I transplant into the seven gallons smart pots.
