Some nutes will become locked out when they are introduced to a foul ph. Its kind of the same reason you don't mix 2 part nutes with eachother. Beneficials can be killed when introduced to water with a ph too high.

When I get some money I'm going to order a PH pen, but for now all I can do is watch the plant for signs of something going wrong. I covered the medium and the algae has disappeared completely. The leaves have also gone back to a beautiful lush green from being on the verge of turning yellow. Thanks to everybody who assisted me with my problem. I'm sure I'll have a million more questions down the road, so you all will be hearing from me again.
