Looks great, unless your in some kind of mixed organic soil or using time release fert it won’t fade much on its own. I lower my feed toward the end and last 1.5-2 weeks water only so they fade out when I cause them too.
If your new to growing, first off great job so far, but it’s almost always best to wait at least 2 weeks longer than you think to harvest. New growers seem to always wanna cut 2 weeks early. I find majority of stuff I run is done in 65-70 days as long as you have good light intensity.
