My Northern Lights Auto is in the 1st week and I have been keeping the temperature at 75F-81F, humidity at 70%-80%. For the past couple of days I have been noticing some yellow spots starting from the cotyledon. Need some advise regarding this
The cotyledon will naturally yellow and die off... its ONLY purpose is to get to the light first to start drawing in what the plant needs to grow... when the true leaves emerge, they take over and the cotyledon's job is over... No worries!
Cheers!
