anyone else experience this? A few of my girls are already darkening at 3 weeks. I flipped the light July 11 so I am guessing they are about 3 weeks into flowering now.

I agree, although in one or two of the pictures i see maybe little signs of N tox and or overwatering which im turn is blocking P uptake. I maybe see some Mg issue also.
