Hey there very nice clean looking tent! great work. Would it be alright if I offer you some pointers? So a few things. First off, Cannabis plants get most of their growth done when the lights go out. They photosynthesize and store up energy during the day cycle & when the lights go out they fall asleep and grow. I have seen a lot of people do 24/7 on plants and auto's but I myself just think it is not the best cycle for plants to thrive under. I would recommend 20/4 if you want to try a cycle with a higher percentage of lights on than lights off but that 4 hours of dark will really help the plants be healthier. Also, your feed temps are a bit high. It can cause root rot to feed your plants with water that warm. Generally, 68 is a good temp for your solution, We do not want it too warm or too cold. Coldwater will stunt the growth a bit which is not good but too warm and we get root rot and that does a lot of damage which can in most cases be reversible.
Also when we expose cannabis plants to a night cycle we also get the benefit of being able to give them a change in their temperature between lights on and lights off. We do not want to expose our plants to swings of more than 10 degrees less when lights go out or the plants will stretch. Most forms of stress when a cannabis plant senses it will make it feel it is closer to the end of its life cycle than it really is and it will react with genetic responses instinctual to its need to reproduce. In veg and early flower, large temperature swings will make it respond by growing up tall and stretching as its first job is to get up vertically to be able to cast its seeds out far and wide. But once it has finished that vertical growth with photoperiods it is from weeks 4-6 of flower autos you need to watch for it, Its responses to stress have no changed. If we now open up that temp gap to more than 10 degrees less when the lights go out it is going to now send extra energy into the budding process and resin production. Now that it has finished its job of getting tall it wants to form up nice big flower clusters to produce seed in & get as sticky as possible to attract pollen successfully. So now exposing it to stress signals will induce this response instead of stretching. This is why managing our temps is important to truly get a good craft cannabis finish on our product and timing it is very important.
If you haven't already, Research VPD and how it relates to cannabis growth. Vapor pressure deficit, Also grab yourself a PAR meter & a thermal laser temp gun like a fluke 62 MAX to better read your plant tops and get more potential from your lights onto them.
