First-timer with a full Mars Hydro setup (TS 1000 & 80x80x160 Tent)

I know Autoflowers don't need to be repot, but I did it anyway. Instead of the Terra Light Mix from Cellmax, I've poured their Terra Soil Mix and choose bigger pots : - 4X20L. (that comes with the full setup) - 4X5L. (as a foreseen gift for Mr. Smee) Because... yes... finally... eight plants... repot surprise... Day 8 I've watered the new soil step by step with 1.25L of tap water to let it time to absorb it properly before moving the girls. After that, another 1.25L but with the Green Buzz stuff. 🎼 To not bring them too much stress, the repot session was made under Chopin's Nocturne and Yann Tiersen's Amélie Poulain Soundtrack. Day 9 In the morning, seemingly, the soil was wet enough. To avoid overwatering, I decided to put them on a diet today. 🎼 I served them Madonna 80's bangers for breakfast instead without let them even know that they was that close to get Cyndi Lauper on the menu. Paul Simon and Billy Joel was served during the night. Day 10 The soil was still moist enough this morning. Once again, it didn't need more water... Before night time, still enough moisture 😳 🎼Phil Collins in the morning. Cat Stevens before bed time. Day 11 OMG! Still. Didn't. Need. Water. Neither in the morning nor before the night. 🎼 To make them thirsty, I've try Limp Bizkit in the morning and Deftones in the night. Day 12 Either someone come into my barn watering my girls during the night, either they still have enough in their pots, because the soil was still humid enough. 🎼AC/DC in the morning. The Rolling Stones in the night. Day 13 Even facing the recent needs in water, I decided to visit my local grow shop with Mr. Smee to bought me the 225L Flexi Tank... and I found some other stuff, like pH buffer and so... 🎼 The 7th Symphony of Beethoven in the morning but the Jefferson Airplane for the night, because an afternoon with Mr.Smee easily put you in that kind of mood. Day 14 A little worry about the soil pH level, I had to flush the beds a little bit. But today, back to normal before night time after a pH downed to 6 on tap water without any nutriment to let the soil stamped. To be honest, it was quicker than I thought. Soil was at 7.7 yesterday morning. I was able to stabilised it tonight at 6.5, 6.7ish, depending the pots. I also noticed that the girls in the 5L. pots was a little late compared to their other sisters in the 20L. ones... So, as put on photo, I've decided to give them some high and put them in the center of the room, right under the light, for more PPFD. 🎼Today was dedicated to Good Ol' Classics like Handel, Pachelbel, etc... Thought that was adequate to avoid more stress. Back to big fat rock tomorrow for another week if everything looks good. So far so good
