My soil tends to bring my pH down ever so slightly. Different soils, different chemistry. Lowering your watering pH down past 6.5 can be harsh, and depending on what you are lowering it with, it could damage the microherd. Don't do anything in the extreme. Take it eeeeeeasy. :jointsmile:

My nutes (BioBizz) bring my pH down, but earlier in veg when I wasn't using any nutes I lowered my pH with a dab of phosphoric acid. You have to be careful with that stuff. Cider vinegar is probably safer. I took my pH from 7.5 to 6.8 and that brought my run-off water to about 6.5-6.6. Now my nutes do it for me and I don't have to bother.

Your mileage may vary but this is my experience and my jab at it.

Be sure you are not over-watering, droopy claw leaves and odd spots/colouration could be because of that, but it is hard to know without a photo and more information. Fill out the troubleshooting form if you do want more help with this.

Much luck.
