I have these strange bubbles on my leaves, and after hours of searching have found nothing about them On the web. Its only on some leaves, and affects no single particular area that I can see. Just randomly here and there.
Well I know it's not the light, the top leaves are fine. LED light 16" away. No heat on my hand when I hold it over the plant for 30 seconds.
temp is 78 for 20 hours of light, 70 for 4 of dark. Veg stage Obviously.
Soil grown. Nutrients are right (I believe anyways... 30-10-10 for veg), proper Ph for the nutrient water.
Relative humidity of 60% - 70%.
Air circulation is as good as it can get. Oscillating fan not directly pointed at plant (wind still rustles leaves, but avoids wind burn) and an out take fan to remove stale air.
Only have 1 going at the moment, as its only for personal use.
drainage in the soil isn't great I'll admit. But its not bad either.
Any ideas?
