I noticed spots on some of my upper leaves but I’m doing everything correctly…temperature is 77, humidity is 50% organic nutes and watering is perfect, ph is at 6.0 lights are great so WTF!!! SO, I recently put in a water softener and I thought that’s the problem except stupid me I’m using spring water I purchased at Walmart. I discovered that using reverse osmosis spring water (which thats what it is) along with a ph of less than 6.2 will create a deficiency of Calcium. So there’s the problem. I will use a stronger cal/mag supplement and make sure my ph is at least 6.3 so the roots don’t block out calcium. Just thought I’d share that info for someone who cares.
Just let her grow man.
Lol I was riggity wrecked when I commented here… didn’t fully read… my b.
@Marijuana_dan thanks for sharing and you are correct in that if you use RO or distilled water you must add in Calcium/magnesium
