Original Sour Diesel - coco grow

Light power consumption: 260 watt Hi fellow growers! Three weeks into the flowering stage and everything is going well. The plants are looking healthy and the buds are starting to develop. On day 68, the first small trichomes became visible to the naked eye. The plants still stretched quite a bit this week, but it looks like most of the growth happened at the beginning of the week and the growth rate is now slowing down. Tiffany (the one on the right) is a bit stretchier. At the beginning, she received a little less light because the panel on the Mars Hydro TSL 2000 on the right seemed to be a bit weaker. I increased the light intensity on that panel and Tiffany's condition improved a lot; she looks much better compared to last week. I'm using a coco/perlite mix (60/40) that has excellent drainage. However, this week I noticed that it takes quite some time for the water to be absorbed by the medium, especially with Sophia. This isn't because the medium is bad, but because the entire pot is completely colonized by roots. There are a lot of small roots at the top of the medium, and when I look through one of the holes at the bottom of the AirRap pots, I can see a large number of roots growing through the holes. In short, there are so many roots that it's impeding drainage. Despite this, the plants look great, so I don't think it will be a problem. On day 67, I did another quite extensive defoliation session. I also pruned away a few side shoots that hadn't made it to the top of the canopy. I also did some low stress training (LST) and some high stress training (HST) on some of the larger shoots of stretchy Tiffany. I did the same thing on day 69, but from this day forward, I don't expect to do much more LST. On day 71, I removed a few leaves that were blocking bud sites. The plants are transitioning to the 'bulking phase', so I will be more reserved with defoliation from now on. Most of the training and shaping is done! At the beginning of the week, I switched to the preflower mix: 0.35 ml/l of each component of Terra Aquatica's FloraTrio. On day 69, I changed the reservoir again and adjusted the nutrient mix once more: the flower component is now the main component. In the coming weeks, I will reduce the nitrogen supply even further. I really love those alien-like grow hairs and this is the fun part of the growth: there isn't much to do except watch the buds develop. Thanks for stopping by and happy growing!
