The “Grow Schedule For Soil Growers,” http://www.ilovegrowingmarijuana.com/grow-schedule-soil/ calls forPh of 6.2 and 6.0 with the last couple of waterings of 6.5.
I tried this method and it eliminated all problems that I had with flowering, My only problem was getting the PH down to where I needed.
It took a lot of water and Ph down as the Ph wouldn’t change until all nuitrients were wash out.
I realize that a Ph of 6.5 is optimal but I always run into deficiencies of different sorts when I try and maintain a 6.5. I believe it’s because Ph tends to climb over time until it’s unhealthy for the plant.
The Schedule for ILGM saved my crop. Now, I’m being told that I’m wrong and that I need to grow at bloom at 6.5
