Question for anyone interested
Foliar feeding. Does it make a difference if you do it when the medium is wet or dry?
My instincts say that if you do it when the medium is dry, the plant will be thirstier, and may therefore absorb the nutes more readily through the leaves. But this is conjecture.
Anyone know?
I Saw your question and went out looking for a possible answer. I realized I alsa had the same question.

"Photosynthesis Takes Place in the Leaves
Plants and trees are autotrophs, living organisms that make their own food. Because they do this using the light energy from the sun, biologists call them photoautotrophs. Most plants and trees on the planet are photoautotrophs.
The conversion of sunlight into food takes place at a cellular level within the leaves of plants in an organelle found in plant cells, a structure called a chloroplast. While leaves consist of several layers, photosynthesis happens in the mesophyll, the middle layer. Small micro openings on the underside of leaves called stomata control the flow of carbon dioxide and oxygen to and from the plant, controlling the plant's gas exchange and the plant's water balance.
Stomata exist on the bottom of leaves, facing away from the sun, to minimize water loss. Little guard cells surrounding the stomata control the opening and closing of these mouth-like openings by swelling or shrinking in response to the amount of water in the atmosphere. When the stomata close, photosynthesis cannot occur, as the plant cannot take in carbon dioxide. This causes carbon dioxide levels in the plant to drop. When the daylight hours become too hot and dry, the stroma closes to conserve moisture.
As an organelle or structure at a cellular level in the plant leaves, chloroplasts have an outer and inner membrane that surrounds them. Inside these membranes are platter-shaped structures called thylakoids. The thylakoid membrane is where the plant and trees store chlorophyll, the green pigment responsible for absorbing the light energy from the sun. This is where the initial light-dependent reactions take place in which numerous proteins make up the transport chain to carry energy pulled from the sun to where it needs to go within the plant."
@Emilya Is right on the stomata, should be the ones incharge of "water" or "foliar feed" absortion/regulation. My only guess is that the best time to foliar feed is during the photosynthesis period or day time.
Many farmers like to water really early in the morning and later at sunsent, Im not sure about the reasson behind it but the sun being to hot in the middle making stomata shut to avoid loss of liquid in the plant could be a reason.
I foliar feed everytime I water the plant.
