So it seems I've neglected the thrips and they got some good damage on the lower fan leaves. Nothing that could have a big impact but enough to be noticeable. I done two rounds of leave washer using Dr Greenthumbs Reset and removed the leaves that seemed too damaged or to old and low to make any difference to the plant.
They are 100% into flower stage going quickly from only few white hairs coming from the stalk pistils to small flowers everywhere in only few days. They are growing really tall with the #3 surprisingly going near to 80cm tall. I'm guessing they are still going to stretch more so I had to do some adaptations on my current setup to allow more vertical room for the light. I'm planning to replace my fan and carbon filter as it's too noisy and the smell is starting to being noticeable outside the tent. I'm looking the Phresh EC Hyperfan V2 as I can integrate with a climate control later on depending on $$$ and an additional Hyperfan for air intake as well as I don't have any fan blowing air into the tent, only out.
I'm pretty glad with the overall of the plants. They are growing strong, tall, and bushy with several bud sites. The whole setup seems to be working good. The size of the tent could be bigger but I believe that I'm using the given space in the most efficient way possible with few gaps on the mesh to be filled as the branches grow. I guess that I'm not coming back to auto flowers anymore. Those plants are way bigger and stronger than any of my previous autos were. If they put on this strenght towards the flowers I'm looking foward at least 50% more at the scales with just few weeks on top of the autos.
