MY FIRST DWC : Sweet Zenzation

sweet zen got a little affected by the water bubbling over... was quickly correctly and she was washed with water hydrogen peroxide and dish soap... shes bouncing back quickly. got a ppm meter today and checked... my water is about 100ppm and my reservoir is at about 900... first DWC, read online it should be at about 600, i followed the cutting edge solutions chart at 100% strength and the roots have been submerged in the solution before and seemed to love it, so i'm gonna put my faith into cutting edge with this one, at least with these two phenos... anybody got any tips on if this is somewhat normal? Readjusted the solution to a half strength for this week and next of seedling stage. also i'm really enjoying the smell of these nutrients over using organics LOL 1ml of bleach every 3 days switched out my heat humidifier for a cool one and my water temp dropped significantly. seems around 68-70 degrees PPM 11/30/23 - 573 12/1/23 - 547 12/2/23 - 529 readjusted to 658
