The plants are beautiful, and there's already some lateral growth developing which I'm super happy about. Still got no idea what to do about the temperature and humidity, but I hope it gets better once the plants are in larger pots
--
UPD: it seems like bigger pots actually did the trick, and we're currently at 24.0°C and 50% RH! As for the growing medium, I used 8 parts Canna Terra soil + 2 parts perlite + 1 part Plagron worm castings + a little bit of 1:10:1 bat guano. I'm gonna give the plants a few days to adjust to their new homes and probably start giving them extra nutrients next week
Lots of things happening this week!
The plants have been repotted and they look happy, except some leaf discolouration on one of them. I suspect it's nitrogen deficiency cuz the plants didn't get any nutrients during the first two weeks, and the soil I used in the nursery pots must have been depleted as I reused it from my previous grow.
Anyway, I'm feeding them with BioBizz Bio-Grow now, 2 ml/l and planning to increase it to 4 ml/l by week 8. No more root complex; still yes to a little bit of calmag just in case.
Temp and humidity been pretty stable at 25C and 50%, respectively.
There's some pre-flower pistils on both plants now, so I'm starting LST before their stems get too rigid. With LST, the plants are perfectly in the middle of my tent now and must be getting a little bit more light!
UPD: turns out the 'deficiency' was more likely an excess of nutrients, so gonna be giving them plain pH-adjusted water for while
The main stem of one of the plants snapped when I was adjusting LST at the beginning of week 4, but I repaired it immediately with some tape and a toothpick and it worked wonders! That plant is now taller and less bushy than the other one tho
There's lots of new healthy growth so I started giving them a little bit of BioGrow again and amended the soil with some 1:10:1 bat guano
Left them alone for a few days, so they dried out a bit but should be ok now. Should be ready to harvest soonish!

Got impatient and harvested them on day 62
I said to you, but will advise one more time !!!
If you overfeed with nitrogen it cuts out calcium, when calcium cut out all other nutrients are struggling to be absorbed, especially magnesium, that's why they go together.
Now your soil is full of food, you were adding CalMag, but plant already shows signs that can't uptake all, so build up is forming.
Just 6.3 pH water , dry out, water, dry out, water. Only then you can return to BioGrow and most probably open bio bloom too by that time.
All the best !
@AsNoriu, got it, thank you so much!! I actually didn't give them any BioGrow until I repotted them, but when I first planted them in their nursery pots I reused some of the soil from my previous grow; like the parts of it that weren't penetrated by any roots. Now I see it where the build up is coming from: the soil I used was likely packed with all the nutrients that the previous plant couldn't absorb. I'm gonna stick to your advice, and given that now they got access to lots of fresh soil, I hope they recover soon! Thanks again for your input :)
