Corrosive Acne

[Student Of Life]

No clue what this is. Friend of mine told me it was the result of salt buildup, but after having flushed everything very thoroughly a couple days ago, the symptoms haven't stopped showing up. They're only present on a few of the girls, but I'm still worried about it since I've yet to correct the cause of it.

Checked for mites with a 100x scope, nothing showing up. Underside of leaves are clean too. Feeding 1.2 EC, 5.9 pH. Humidity 60-70. Temp 75-80.

That makes perfect sense. These symptoms show up on the girls nearest to the fan. I'll have to closely examine the girls in the back thoroughly to double check, but I think you nailed it. Thanks mojave

I agree, mechanical damage.
