This is the week when the grow went from good to bad. Me not dealing with the low ph in the runoff became a big issue. Not only was my piece of crap Vivosun ph pen reading high, even after multiple calibrations, but the low ph was even worse that I thought. Flushed her with six gallons of 7ph water and was able to get the runoff above 6, but the damage is done. Had similar issues with her sister Gorilla Glue. Damaged yellowing leaves started and the bottom and moved up. Fed her a full course of nutes, and the ph and EC are within range, but the damage is done.
