Yep, all pots have drain holes and no, the yellowing does not occur but I did fail to 'cut back' the stems etc. prior to the last winter.

As for PH....I've never committed to that level of detail since I stopped breeding Malawi Cichlids

Anyhoo....here are a few iPhone shots taken shortly after the rain sibsided, not the best quality but they should give a clue to the trained eye as to what some of the plants are.
