Blueberry Auto- Zamnesia Seeds

Pictures are from day 15, right at the end of week 2. There has been a bit of a heat resurgence where I live with outside temperatures reaching 30 Celsius and it getting almost as hot indoors, therefore the temperature in the tent for the last 2-3 days has been a a couple degrees above my ideal 26 degree temperature, however it should cool down soon and I can get the temperatures back under control. I have been using my garden highpro fan more and more throughout the days to give the plants wind. The youngest plant is now also in veg and showing a weird leaf curl (mutation?). I water the pots with around 1L every couple days whenever the soil dries out, however I will now also start putting water into the drain trays to get the fabric pots wet from the bottom for better root growth. The water is supplemented with the Zamnesia x Bionova X-Cel from the Monster Bud Boost Pack (NPK 1-0-0) at around half the recommended dosage (2.5ml per 10l), as I want to avoid nitrogen burn. The water is pHed at 6.3. I will look into LST soon and maybe even consider experimenting topping/ defoliating on my smallest plant later as well. Any thoughts from you guys on defoliating/ topping for autoflowers? Thanks for reading and have a great week!
