I checked my plant and the fan leaves are dropping pretty bad, it's been 2 days since i've watered so i haven't over fed and i scrapped the top layer of soil and is still cool and moist. the temp have been between 21-25 degrees celcius during lights on and between 16-20 lights off and the humidity is only between 35-45 % low but apparently its best that way when growing with leds. im 30 days in veg. im sure it's nothing but considering its not over or underwater and probably not to do with the environment it beats me, also the light would have come on anywhere from around 4-2 hours ago so it's not sleeping or dropping at the end of the day since its the start im on 20/4 light on/off so there's all the details i thinks necessary
