hello i am a starter to advance nutrients and was wondering if the ph range should be kept at 5.6 like they suggest or should i leave it 5.8? please let me know if there are any special gains from keeping the ph at 5.6? appreciate all the help
You can actually go as low as 5.3 and still have good nutrient uptake. If you keep it between 5.3 and 5.8 you will be fine. So 5.5 is a nice mid point.
