hi,
It is my first grow planting White Widow Auto,
On day 18, i found some stains on the leaves and thought the soild PH value was too low (around 4-5) or light was too close (using 40W LED at about 10" distance from plant). After adjusting PH to 7 and light to about 20" distance, it seemed like the plant was recovering. However on day 25, the new leaves still show the white stain. Is it the nutrition issue? PH issue? or light issue? Been browsing for the causes of the symptoms, and most causes seem to have the same symptom. here are some photos. Any help and suggestion would be greatly appreciated!
Day 18 Plant height:2" width:1.6"
COB 40W 6000K actual power consumption at 20" distance
8W LED Plant light E27 *3pcs (focusing on 460nm and 640nm
Day 25 Plant height to 2.4" with new leaves, but still stain on new leaves.
COB 40W 6000K actual power consumption at 20" distance
8W LED Plant light E27 *3pcs (focusing on 460nm and 640nm
