So just checked my plants as I turn them everyday ad have noticed this
strain : Heavy weight fast and vast
Grow medium : Plant magic Supreme soil 70/30 perlite
Pot size : 8ltr
Feed: water only
Age: 14 days old
Temps Hi: 26
Temps Low : 21
Humidity 65%
Light: 600watt MH Height 2ft
Any ideas on what it could be? I have 4 plants and only 3 are showing this problem with brown spots. The new growth is fine and has no issues, nice and green.
Thanks for any advice.
