This strong ppm thang is new to me as well. I am using DM gold and I have never ran my nutes higher than 950 ppm be for trying this stuff. I think in my case its the nutes. The ones in the tray didnt seem to like it much over 1K ppm. On the other hand the plants in the UC have seen weeks of 1300+ ppm and havent shown one little tiny bit of tip burn. Its gotta be the nutes. Well we shall see. Im thinking of running my 8xl and a 4xl side by side with DM gold vs ? may be I'll try advanced.
All in all your plants look to be the "SHIT" DG just keep it up.
Good luck
