Hey there, I suggest you maintain your current schedule which is fine unless the plant starts showing signs of stress for example Mg deficiency. In that case , lower the light schedule to 18/6 maximum. Otherwise it looks totally fine. You have great photographs ! Hope this helps ! 🚀
@Growerlighting Hi mate 20 / 4 is great for autos it really seems to be the sweet lighting cycle that provides both rapid growth and just enough rest for the plants Keep up the fantastic work
