I'm pretty sure no lockout. 6.3-6.5 runoff ph is usually golden for me. Even the cutting in plain water started looking like that about the same time. I added a few drops of veg nutes and it greened back up. Another cutting showing deficiency greened up when I buried the peat puck in fresh FFOF. I added fresh soil to the top inch of the pot and I'm upping the bloom nutes. I raised the light a few inches too, hoping to reduce any stress. They are bushing up like crazy, so hungry is my thought too. Thanks for responding!
