Update with my foliar spray.
This pic shows 2 plant that were severely yellow this past Monday. I spray it twice with Miracle Grow mixed per package direction (1
Tbsp per gallon). There was some improvement by Saturday morning. Saturday (yesterday) I sprayed the plant with the new mix (5.6 Xs stronger) of Miracle grow of 80g MG; 4g SOP;, 2
Tbsp Epson salt; and a pesticide. In a little more than 12 hours there has been 100% plus improvement of the color.
This next pic is a closeup of one leaf. On the far right is a steak of yellow. That was what the entire leaf looked like last Monday and shows how much the foliar spray (nitrogen) improved the color.
Next photo shows a leaf that lost all green color and was white. The 1st foliar spray (weak package direction mix) added a little green around the edges. The 2nd spray filled in about 25% of the green. The new mix foliar spray in just 12 hours filled in the leaf to about 75% green.
The following photo is interesting because the sufficant (Ivory dish liquid) residue has caused the the dew to stick to the leaves this morning in small tiny beads.
This was one of my immediate needs for a better foliar spray for bananas. And, for products to be 'off-the-shelf' and available locally.
