Thank you for the info chronic chrissy. I just replenished with fresh water and the ppm's went down. Yesterday they were at 1800 and today after fresh water, 1530 ppm ( tds ). I tested for saline and the ppm came up at 1030ppm for saline. Based off the numbers I should be ok, right? Tomorrow it should be down to 1100 ppms and the saline should be lower. I don't replenish with nutes until the tds's get down to 600. With the recipe I am following it gives me about 600 ppms per gallon so that is why I wait to give fresh nutes. They are showing flying V's so they look good. Pistils are starting to show more. I can' t wait!

Happy Growing!!!!!
