Optical Illusion? Wishful Thinking? Possibility?
I Just came in from Foliar Feeding my citrus trees. The first trees had some yellow leaves with green veins. Not all the leaves just a little. By the time I came back to the first tree an hour later it looked like the leaves were already starting to green up. The green veins looked like they had gotten noticeably wider. This was done just before twilight so both the color spectrum and the intensity of the available light had changed considerably.
I sprayed them with Liquid Kelp and just a little bit of Epsom Salt. Is it possible that there could be a slight change that fast or did the changing light just play a trick on me which will be evident tomorrow morning?
