Hey mate, I am also growing Zkittlez OG auto . Both indoors and out, testing a different technique on each plant as I go, it's been an experience to say the least. I have advice and you should follow my grow, I'll follow yours. First thing I was curious about is do you have a humidity monitor because your plants 'seem' limp and the soil appears that it is or may have been quite overwatered. If not just keep this in mind when it comes to watering that you shouldn't follow a 24 hour routine cycle, only water when the soil is dry and pulling away from the sides of the pot. Also, I've been looking at your current pictures and it appears to me your plant is ready for some defoliation or trimming. Message me =) 😎
