So I watered my sprout yesterday so I could get good pH readings. Got the kit today.

The soil is sitting at 6.6. The runoff is 6.8. Tap water is 6.9 and the distilled bottled water is 7.0.

So what should I add to the water to get the pH 6.3-6.5? My kit is saying add either iron or aluminum sulfate to acidify the soil. Which one should I use to mix in the water?

Looks like I'm gonna have to hold off on the watering for quite some time, though. The first leaves are curled down a little. Good news is it's growing before my eyes. The 2nd node is developing and there is a little dot in there that holds the future 3rd node. :smokin:

Bad news is my 2nd sprout died. The embryonic leaves just couldn't bust open the seed, so it fell over.
