Automatic RQS. Fat Banana and Royal Critical. My 3rd grow. 600w HPS in 120x120x210cm Tent!

We just had crazy 2 days. First, I thought its gonna be good to rise the pots on a carton box... Then I thoughts it's gonna be even better to water the plant until it starts dripping from the bottom and I took a nap. Disaster. I have some cheap plastic pots that drain the water pretty slow and when I woke up from my nap, the box was bend and tent had a lot of water on the ground. I fixed the problem and I put the pots on top of upside pots. But today I set the lamp to 400W, Fat Banana was defo stretching for more "sun". Day after that, I thoughts that maybe it's gonna be good if she stretch a little. I set up a fan blowing on her every now and then and I go to sleep. Next day I found her laying on the ground, so I had to put extra soil around the stem so she don't break. You can see on pictures from Day 8, she is little bit to the left, a bit to the right. She literally just LST herself. It was funny to see how fast she get up after that accident (see Day 7 pics). Edit from 01/05/2024 or from 05/01/2024 for USA weed enjoyers. Before I was talking about Fat Banana stretching for more light and I gave some to her she respond very good to that. Currently I'm blasting 400W at them from 6am to 11pm. Temps are hot outside generally so inside the tent I have 32C and below. I thought It's maybe a little bit too much for them but they seems to not give a single fuck and they pray everyday for more :) Another thing that I'm worry about is humidity. I never drops below 40% and it sits usually at around 42-44%. I'm putting wet cloth next to the plant for that extra moisture but Im not sure If that's gonna be enough with 3-5 more plants and 600W. Tomorrow Im going for more soil and Im gonna fill up the tent with pots. Originally I was thinking about 9 plants, because that's how many pots will fit there but now Im thinking about 5-6 because of space around. It's gonna be pain in the ass to work around 9 flowers in super crowdy space. Also, these freaking 18L pots I have, they hold 25L of soil no problem. Edit from 03 May 2024 Last two days plants are praying, that's it. I'm just watching. 32C and humidity drops to 30-35% because I close the tent more than it was before.
