I wasn't suggesting that you didn't water or feed the roots. Just that you supplement a reduced root watering schedule with foliar feeding. Could this possibly reduce the 'need' the plant (from the soil up) requires from the roots? Roots would still be healthy. Just not as important to feeding the upper plant. In other words what I'm suggesting is that you give the roots a break which could allow them to survive being root bound (and thus the rest of the plant) instead of just continuing to feed the crap out of them as normal and have them grow even more root bound. Like doing a lot of upper body weight training but reducing lower body training. Body still survives but the upper is stronger.

I understand that the leaves can't absorb enough to survive off of, but they can absorb some. Probably quite a bit if pushed to do so. Question is whether or not it would reduce the stress of a plant being root bound to a point where it would help prolong or improve it's life. Guess that's why someone invented the word "try". Which is what I may do as the plants to this point had been perfectly healthy. Perky. Last few days a little droopy. Got me worried.
