I posted this to another thread and it was suggested that I post it here as well:
You really can’t grow at your best in hempy without a good pH meter.
In hempy, aim for 5.8 after mixing all nutrients. It’s okay to go as low as 5.6 once in a while, but since anything in the reservoir will drift up, never go over 6. Really try to hit 5.7-5.9 in flower. The plants will need daily fertigating, so it’s important to be consistent and accurate.
Another point - If you know that your water quality/pH is consistent, you only really need to measure/verify your final pH whenever you increase the fertilizer dose - it shouldn’t change in-between. So it isn’t as labor-intensive as one might think. It isn’t like maintaining a DWC or Flood/Drain reservoir.
And in said other thread, you analysed the various nutrient levels of a certain mixture suggesting some were too high/low, etc.
Can you lay out what we should be looking for for targets?
