Day 131 from seed. Two weeks of flowering complete, six weeks to go. I recently fed 18-18-21 Miracle grow Tomato food with a dip of Earth Alive Big Blue Alga and blackstrap molasses. Stretch is almost complete and the buds have formed. A smaller, more stout plant than my others. I moved my thermometer and am finally getting canopy readings, wow its hot! I have to monitor that.
@Jumpingjack, personally I think LST is the better technique, as there is no damage to the plant. Works really well outdoors.
Topping is good too, but more work and slows growth down. You need to be patient and allow it to recover.
