Well........I think you is at that stage of the game....I recycle all my soil now, so I just cut the nutes rather than a traditional flush.
But.....my thoughts are that this lack of drainage you mentioned is where all your ills are at. My experiences in my own garden tell me that drainage is way up there in the importance stakes.....poor drainage leads to roots not getting enough O2, and with poor roots, you're facing a Sisyphan struggle.
I see what the coco people get off their plants, and that's all about drainage (in my mind anyway).
But, that observation aside....and on the flush, I'm just a little hesitant at recommending your pour large volumes of water in your pot when it's just going to sit there and possibly slow things down even more....I think it's more important for her to finish well, in top gear, rather than risk giving her a whole new headache of sodden roots to deal with .....I'd be more tempted to wait for her to start complaining about being dry and then just add enough water (with perhaps a drop of washing-up liquid as a wetting agent) to get a bit of run-off.
That's my gut feeling on this.....hopefully one of the more experienced heads will pop in and contribute their opinion.
