Leaves turned yellow after molasses
« on: May 28, 2020, 12:21:14 PM »
I recently foliar fed my wax jambu and atemoya plants thru the leaves with 1oz unsulfured grandma brand molasses and 1oz of fish and kelp emulsion in a gallon of water.  These plants are in pots.

After 2 weeks, some of the leaves are turning yellow with green veins. From the leaves, it looks like a chlorosis of magnesium. Is it deficient in magnesium or iron?

Anyone with similar experiences? How do i correct this?

My atemoya's also have that and i didn't feed them molasses...i fed them dolomite on the soil but mine look worse than yours.

I thought it came from the ultra high heat here but i have no idea...the one on the hottest spot has very light yellow leaves now, almost white...

did you add a surfactant or wetting agent?

my 2 cents is that it's not related to the foliar spray at all....i would be concerned about possible iron-deficiency chlorosis caused by alkaline soil conditions.

though that might be a bit strong of a solution (2 oz total per gallon).

I thought about that too (soil pH). I dont believe wax jambu and atemoya are pH sensitive plants so they can tolerate in the 7 to 7.5 level, correct.

Wax jambu and atemoya like high ph .Atemoya likes limestone and wax jambu sodic soil wich has a ph of 8,5+.
What i think it happened its that you feed bacteria with sugar and they used all the nitrogen .
After bacteria dies ,the plant should get available nitrogen again and more than before.
