I agree, I change my res every three days now. Partly because of a lack of a ppm meter and mostly because I like to tinker a lot.
It keeps things cleaner and ph steady. I always wash my tub every res change too, my plant loves me for it
Not knocking what your doing at all bro!
Those last pics made my mouth water a little, great looking sugary buds and leaves. Keep it up!
you're a wise grower, yarddog!
