I dont feel like investing in more advanced PH meters, they cost around 60$ where I live.

He said I can water the plant and then check the PH of the water that drain from it, is that correct?
yes, its good to check your feeding water ph, remember it, then water your plant & collect the water from the drain holes & measure its ph, (called soil runoff ph), & this should be between 6.5-7.0, but shoot for 6.8. any time u add ferts to water the ph will drop. from my experence: my runoff ph was 6.4, so i used water w/ a ph of 7.2-7.3 to bring it up to 6.8. most tap water should be around 7.0, mine jumps between 7.0-7.2. u should look on ebay the have digital ph meters for 30$, & trust me ph is one of the most important things to keep track of. like this http://cgi.ebay.com/New-pH-Meter-Aqu...QQcmdZViewItem or this search http://search.ebay.com/ph-meter_W0QQ...csZ2QQsbrbinZt
