Repotting Phrag. Cardinal needs help, leave in s/h or go with a bark mix?

Becca - feed at a low rate, but you HAVE to feed!!!

There are some elements that are translocatable in a plant, but others that are not - calcium being a major, critical nutrient that isn't. Most folks can get away with not feeding for a long time because calcium, magnesium and iron are common in the water supply, and the plants can share what they already have of the others with new growths, but as you're been using RO water, you ain't been givin' them nuthin'.

Personally, I recommend the MSU RO or K-Lite formula at 50 ppm N at every watering.

Ray, would you do any pH adjustment, or RO + fert (@ 50 ppm N) and good to go?
