At the end of Week 6 I continued mainlining and training the plants. The 6 larger plants have been topped 3 times for 8 colas. The 3 smaller ones have been topped twice, and there's some asymmetry going on with two nodes on one side of the manifold and one on the other. Of the 9 plants, 6 are Indica dominant, larger with very stubby and broad leaves. Three plants are smaller and have thinner leaves and looked like weaklings, but they have all responded well to the addition of Ca-Mg to their feeding regime a couple weeks ago. I'm new to coco coir and these plants are growing slower than I expected, probably due to spending their first month outside in chilly late spring weather. I'm feeding them about 750 ml every two days, and I estimate about 30% of that is drained to waste. I still have less than 5 gal in my waste reservoir after a couple weeks. I think they'll finally be ready to start flowering soon.
