Day 74 from seed. This is similar to my other Hash Plant but not quite as progressed because I caught it. I bit the bullet with both plants and majorly flushed the soil (five days ago) in an effort to regain control and reset it a bit. I will be back to applying my typical veg. feeding after it dries out. The lower the leaves mat have gotten worse, from lack of nitrogen, but the tops may be stabilizing. Just trying to be patient and not overfeed/overreact/overwater. I have around 5-6 weeks of veg. to play with.
@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.
