MY FIRST DWC : MASTER KUSH

Full strength Cutting Edge Solutions Nutrient Line Master Kush is absolutely loving the DWC setup so far... Noticeable but small growth in just a day... Growing bit by bit each day.. looking great and loving her set up. 11/28 - reservoir was dumped to just at net basket level... had it soaking for a little, now i'll let the roots breathe. 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? *after doing some research i do believe that i will be cutting down the next fill up to about half strength. Readjusted the solution to a half strength for this week and next of seedling stage. switched out my heat humidifier for a cool one and my water temp dropped significantly. seems around 68-70 degrees PPM 11/30/23 - 650 12/1/23 - 549 12/2/23 - 537 readjusted to 665
