Maybe nothing, but......
Background- This is my first auto flower grow......
White Widow AF Nirvana, she's 18 days old today
4X4 tent
400W hps light with 4" inline fan and duct attached, 18 inches above the plant.
Medium - bottom 2/3 of 3 gallon pot is FFOF with extra perlite, layer of 1 tsp Great White mycorrhizae, top 1/3 FFHF
No nutrients have been used so far, just watering with ph 6.5 tap water, set out overnight before use.
The spots that concern me seem to be localized to 1, maybe 2 fan leaves. She appears to be doing good and healthy
otherwise. Photos attached.......including my tent.
My first thought was water drops on the leaves, under the light may have cause......but I don't know.
