i buy 1cc needle-less syringes by the 100 pack on ebay. a bit easier to measure out accurately. once you get used to the new ph dwon/up, you can almost guess how much to add to get your pH in range.

Do you add straight undiluted ph up or down after you add nutrients to any bucket, container, resevoir?

A drastic spike in ph can cause your nutrients to precipitate is all I'm saying.

Something to watch for

Correct. Simple way to help this is to make sure you swirl the water in a circle just before you drop the pH down. The constant movement of water helps prevent precipitation. Ya always feel bad when you see a cloudiness as you drip the pH down. That's all ya stuff falling out of solution

I was not liking the swings with RO so I started to use tap water or a mix of 70% RO 30% tap. the alkalinity/hardness will keep it much more stable. For the tap water I use a hot tub garden hose filter or i bypass the RO Membrane and just use the water that comes from the sediment/charcoal filters.

What is the PPM of the tap water you have?

Ive been uaing a 50\50 mix of high ppm tap (450) and rainwater bringing it to around 225 adding canna coco nute and cal mag.. i ihd it down to 6 1 and it was above 7.2 the next day..so i phd it down again and its nack up again but i also only did a small batch 2g and not in my actual 25 g res so idk if that could play a part or not needing some insight being my seedlings jus broke ground and will be going automoated here soon
