Good morning Willie, sorry to hear about all the pain you have going on. Hope it will soon pass. Yes, it is cold here too! 29 overnight and only 30 now. Slight wind which makes it even colder. I guess all my early leafing plants in the yard are full of dead leaves now. Happened just like this last year too. We shall remember these cold days when it is 95 and humid this summer, right?
You are right to concentrate on the discus tank, the growing babies need all that care, but as they get full grown you can lessen all the daily water changes and many feedings. I do every other day now, and feed 3 times a day.
Hope you all have a good day ahead!
Barb
