Can anyone help me out. I'm a 1st time grower..im. Growing 4 personal plants..they are 10 days old today and I have them under 2 flourascent lights.. One T-5 HO 2000 lumen 24watt 6800k Nd the other 17 watt 7800k..they look healthy but the tops of my leaves have some little speckles of what looks like white powderish spots.tht come off when I rubbed then off??? any idea to what that is?
Could be powdery mildew. How wet are you keeping them and what is the humidity in the room? If the plants are to wet and the humidity is high, then your are subject to several molds and mildew. Good luck
try milk 1 part milk to 9 parts water spray plants under and on top sounds like powdery mildew have never had it but known other growers who have plus the vitamins and trace minerals the plants do like I do spray mine once a week since they really get dark green in veg and they love it where do u live? is there a higher humidity where u live? my i live in a semi arrid enviroment no humidity issues.
