Yes, I do. Everything I need is in the Advanced Nutrients Micro, Grow, and Bloom. Like I said it only happened over a 24 hour period when I couldn't montior the PH levels. It got down to 5.1. I just order a PPM meter I'm not waiting till tomorrow lol.
If things get worse I will just flush with just PH'd water until Thursday when I do my normal flush and feed.
