The time period between watering is too short for the amount of water you are giving / the amount of water you are giving for the times you water in the week is too big.
Cannabis roots need enough time in wet/dry cycles. They thrive in dry medium looking for water resources.
Then again, one could say your pots are too big in the first place, your automatic plants won't have enough time to occupy the medium space with roots, next time, I would advise to give the girls smaller homes, not every bitch needs a castle! You have 14 liter pots and your roots are maybe at 0.2 - 0.5 maximum 1 Litre pot levels. At this stage I would spray water directly at the base of the stem, maybe 200 ml. I know people say that you should put the automatics in the final pot, but I think I would argue to disagree nowadays. Its much more important to have a healthy root system
(This is much easier to achieve with a small pot, with giving them 250ml maximum.) than not having to transplant them. With automatics I would transplant them 1 time, from their seedling pot to the final one. I will use 1 litre pots from seedling stage until the root system is covering almost all of the soil in that pot before I transplant mine to their final ones, but also I am using photoperiodics and not autos, but it's still the same principle!
But of course, your ladies are nice looking!
