Day 67 from seed. Like Hash Plant (II) this one is going downhill. There is an imbalance somewhere, and based on my other grow I suspect it may be excess (of Potassium). I am planning a good water flush to try and restore this plant. I recently fed 0.1-0-5 Earth Alive Big Blue Alga Liquid Seaweed.
@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.
