Black Sugar grow

Had an issue whilst training this week, I forgot to leave a stump on the 2nd topping and when I tried to train it I broke 2 of the tops off. Tried to repair but failed and just cut them off. All recovered, did a bit of super cropping and chiropracting to strengthen the stems a bit more... and today just topped the 4 main tops left to complete the mainline training. From now I'll just be using lst and when necessary some more supercropping, to ensure an even, spread out canopy come flower. All good tho just need to back off on the nutrients as I'm consistently getting 900 to 1000ppm runoff when I'm watering with 20% runoff if more everytime I feed. Also some leaves are a bit too dark so I will drop to around 6ml rather than 9ml per gallon of the a and b.
