Little brown specs?

[mountaineerfanatic]

I was wondering if anyone could tell me what these little brown spots are on the gorilla glue auto leaves. Ph is 6.2. Using general hydroponics flora series, plant is a week old, and using zxmean 1000w led. I only put about a quarter of a teaspoon of each nute. Any help would be appreciated.

Your pH is outside of the hydro range of 5.5-6.1 That looks like the start of a major deficiency to me, and I suggest you adjust to 5.8 pH to see if that stops it.
