IKEA Stealth Grow // The Church, Serious 6, with mobile A/C unit on 1,2 square meters

I started to scrog The Church (left side of the closet). I topped the plants after the fourth node. Of the 4 Churches, I didn't properly top two of them. These two are looking like they are developing the main cola as well as the two side colas equally, so it seems there are three of them. Serious 6 is growing slowly. Two of the plants are staying small and scrawny. I'm wondering if that is the phenotype or if I messed up. And to top it all of, there was an accident with the Autopots :-(( This is the second time it happened in my AP system: The float gauges in one of the trays got stuck and the water kept flowing. The tray overflowed and the water ran all over my wooden floor. This also happened at night and I only discovered it the next morning. Luckily, the float became unstock at one point of time and the waterflow stopped. If it hadn't, 30 Liters of water in my tank would have caused serious issues. I was going to start the 12/12 flowering cycle next week, but looking at the Serious 6s I will postpone it by at least another week. That way the Church can scrog longer and I assume won't fill up the net as quickly as Serious 6 anyway, since it more bushy compared to the Serious 6 sativas.
