So, as we know I've had a few issues with ph that I've been working through and with the help of Fuzzy Duck I have figured out what my issue were and how to make changes going forward.
Knowing that biobizz soil should be buffered to a ph of approx 6.6, I decided to test the theory.
I tested the ph of soil belonging to my Northern Lights. First I tested it before I fed with a new soil ph tester and got a result of just below 6.
I then mixed and fed as normal but without any ph checks or adjustments to the nutrient solution, which I know has a ph value of approximately 5.7 before adjustments.
After feeding i checked the ph of soil again and got a reading of just above 5.5
After 24 hours I checked again as was pleasantly suprised to see my soil ph up at 6.5 and no issues with the plant (it was at this point with the Pe that my issues started)
Now my issues were arriving the day after feeding with high soil ph locking out the micro nutrients. If I had used ph up to correct my nutrient solution I believe that it was sitting in the soil causing the ph to rise above the levels needed for micro nutrient uptake. I have now decided to retire my ph pen and rely on the soil doing my adjustments for me.
I hope this helps somebody else at some point
Big thanks to Fuzzy for your help
More than happy to help out
