Sorry I lost this thread for awhile but finally got back. Your newer pictures of your munchkins look great!! Good work! I honestly don't know much about soil growing but as far as ph goes if you have a pet store near you you can buy super cheap liquid ph testers that will work for you--very basic and easy to use. I have read however that you do not want to use the ph up/down for aquariums for your plants because there are too many salts in those particular ones. I don't know if this applies to soil or hydro or both. I would repot your munchkin in the poorly draining soil asap--I grew some outdoor ones in clay-like soil with crappy drainage and even tho I repotted them as soon as i figured out the problem they did recover but never really thrived after that. They only grew to about 1/3 size of normal. Of course maybe I just suck......
