9/9-9/15 9/10: Plants are growing great. The larger one (but not the smaller one for some reason) has slight nutrient burn at leaf tips on new growth--so, at least I know the Grow Dots are going hard. The medium felt a little dry to the touch so I set up the ACI auto-watering plant bases. Now I'm worried about overflow.... I'm not really worried that one plant is half the size of the other. This summer, I grew some tomatillos and the same thing happened: one big, one small. By the end of the summer you couldn't tell the difference between the two. I have faith that the little one will catch up. This is only the second time I've grown two plants at once, so maybe this always happens. The humidity has been a little high in the tent, but I've more or less been hitting my VPD number (0.8-1.1 for veg). The reservoir has ArmorSI (and half-strength CaliMagic because I can't resist fiddling with everything--no actual sign of calmag deficiency). PH tested every day and adjusted to 5-8-6.0. The res pH has a tendency to drift up, but never more than 6.2-6.3. I have been defoliating here and there because of the higher humidity. The big defoliation is going to happen on 9/12, and then at the end of the week I will flip to flower. I normally would have flipped this week, but because I only got the Grow Dots in the medium 3 weeks ago I need to go one more week. Grow Dots are time release, and set up for a 4-week vegetative phase. The tent is going to get really crowded. It already is. Other than the light defoliation, this has been a really hands-off and problem-free grow so far. 9/12: Defoliated a lot. I defoliate leaves that are: covering bud sites, pressing against the tent walls (moisture accumulation), shaded out by the canopy, dying, or pointed inwards. The plants are very squat and dense, which made defoliation difficult. 9/15: Plants are thriving. I'm using the ACI base and the Blumats. The plants, it turns out, were under-watered from the Blumats on their own. So, I pulled the Blumat sensors higher in the medium (2" under surface). Now, the Blumat drip waters the top half of the container and the ACI base waters the bottom half. So far, it's working great. The smaller plant's internodal spacing is so tight that I couldn't use the red clips--back to tying the branches down with string. It's very bushy and I didn't defoliate much at all. It's crowded in there, but the canopy is actually very even. MOST IMPORTANT INFO: I had completely forgotten that Grow Dots are temperature-release, not water-release. The larger plant started to get nute burn, so I lowered the temperature in the tent (luckily the weather is cooperating) to around 73-75F. It looks like the new growth is less burnt since I lowered the temperature. I wonder if I need to push the nutrients harder later on, can I raise the temp a little bit to do so? What degree of control do the Grow Dots give you? 9/16: Flipped to flower. Lights on 12/12.
