I clicked on your thread to see what new takes/insights a long time grower is using.
Hopefully I will bring something new to the conversation that you might find helpful. Feel free to do the same should you visit my thread. I have been working toward simplifying hydroponics. I feel I have done that, at least for me. Passing this on, not trying to jack your thread, but I think you will find it helpful
When using DWC, I, too, had mega slim issues. That led me on a 2 year experiment with a stripped down version of high pressure aero (>100psi) short cycle feedings ~ 3 seconds every 4-5 minutes. I was never able to produce anything AWESOME, but it taught me a lot. I started developing a modified F & D., which I ran side by side, using the exact same nutes (DM Gold, full AB line) until 2 grows back when I switched to hydroponic research VEG+BLOOM, a one part dry formula.
Anyway, I combined hydroponic concepts of hpa + flood and drain (my first effort growing mmj some 33 years ago) + low pressure mist above the grow medium, and developed a simple to make DIY system that eliminates slime, uses 1/20th the nutes, which are fed during early veg every 45 minutes for ~ 20 seconds 24/7, though night feeds can be quickly eliminated using a simple analog o/o cycle timer as long as you manually reset it each morning.

In the mean I'll catch up with your thread, but after reading about the slim, I thought you guys might want to know about an alternative
Again, apologies for jumping in here. I promise to be quiet now
