Hi, I have two cannabis plants that were planted in the same day (middle of April). Both are cutting . One is Purple Haze (the small one) and the second is Tutankhamun. Both are growing hydroponic (DWC) in the same condition. Electrical conductivity around 1350us/cm, PH 5.7. Growth room temperature 26.5, RH 53%. The roots look healthy in both plants. The light is 250W dual spectrum, cool tube reflector 35 cm above plant tip. Sometimes I use fan in the growth space. As you can see in the photos the small plant looks “tired” and its growth rate is slow and stunted compare to the second plant. Do you know what is the problem according to the photos and the data I wrote?
