Day 19 to Day 22
They are currently on a 48 hour watering cycle and were watered on days 19 and 21. Both times I gave them EC 1.1, a slight increase from day 17. This is 0.9ml/l Gro, 0.6ml/l Micro and 0.3ml/l Bloom, pH'd to 6.1. I also gave them a spray with Epsom salts solution on day 21.
It's been a little colder outside recently but things have been more or less the same in the tent: 21-28°C, and humidity 45-70%. I think I've only filled up the humidifier once in these past four days, it's hardly doing any work now.
All the plants have pistils now. I found it really hard to take any kind of satisfying picture of them, but I was quite pleased with the one above.
I spotted pistils on the second Sweet Gelato Auto today, which would be her equivalent day 18, due to her later start. She's just like her little big sister! She probably has the most leaf area of the four plants, and it is this lovely rich deep green colour. I do think there might be something about fabric pots that helps plants get off to a better start than airpots. I had similar results last grow when I had a mix of pot types in the tent - those in fabric pots grew faster at the beginning. Perhaps because the fabric pots are not so harsh at root pruning? Perhaps I'm doing something wrong and I could improve my results with airpots? I'm not sure, but I am considering ditching the airpots for future grows based on these experiences. There are advantages to airpots too though, such as drainage, and training, so I haven't made a firm decision.
On a photography sidenote, I downloaded the new version of Darktable yesterday to process my photos and I've been getting to grips with that. I've tried to improve this batch of pictures particularly in relation to colour. I had been leaving the camera to automatically get the white balance before now, and I had been fairly happy with the results, showing a warm glow from the Agro bulb. However this definitely gave a yellowish tinge to the leaf colour, and it the plants look ever so slightly pale in comparison to real life, so I have tried to fix it this time. I don't have a calibrated screen so it is difficult to know, I'm not totally sure I've got it right but I think it is an improvement and more accurately represents what they actually look like.

Day 23 and Day 24
Some of the plants will be tied down very soon, they have some nice sidegrowth already. I didn't want to do it too soon, because it has made watering awkward in previous grows when there wasn't much space to get in under the plants, so I've waited until they are bigger this time.
I gave another watering on day 23 with the same EC 1.1 solution. Soon it will be time to start switching the ratio over between Gro and Bloom for flowering, but not just yet. Temperature has been a little higher, typically about 27°C up to a maximum recorded 30°C, minimum 22°C, and humidity 45-68%, usually at the higher end.
I won't be tying the first Sweet Gelato Auto down, at least not just yet. I just measured a height above the coco of only 10cm. I may as well keep it going. It is a lovely, healthy plant albeit very compact, and should still give a nice result, though just maybe not a lot of it. In comparison the Sweet Trainwreck Auto is tallest at 23cm, and the Ice Cool Auto is just a centimetre or two shorter.
On the other hand, the younger Sweet Gelato Auto is growing tremendously well so far and has some huge leaves, bigger than the other plants. It is 19cm tall, and all around much larger than the first one. It was the right decision to start another.

Day 25 to Day 27
I tied down the Ice Cool Auto and Sweet Trainwreck Auto on day 25 to begin LST.
The Sweet Trainwreck Auto folded over sharply and it's almost supercropped - it has a nice knuckle.
Sweet Trainwreck Auto has lots of sidebranching, and budsites starting.
I watered on day 25 with EC 1.1 again. I bumped up the food slightly to EC 1.2 today keeping it on the veg ratio still (1.05ml/l Gro, 0.7ml/l Micro, 0.35ml/l Bloom, pH 6.5). Humidity has swung about a bit about the past few days, and has been between 45% up to a maximum recorded 78%. Temperature has been typically 27°C with the lights on, up to 29°C maximum and down to a lowest 20°C at times with lights off.
Both Sweet Gelato Autos are not tied down, not yet. The first is too small and I might not tie it down at all, depending on how it grows. I should tie the second one down soon but I am not sure quite what to do yet since it's in a fabric pot without any handles. Maybe I should put a belt around it?
