Citrus General Discussion / 4 plants 4 problems
« on: September 24, 2016, 08:59:12 AM »
Hi all, I'm hoping to get some help identifying 4 different problems I'm having with 4 different plants.
I've been into Citrus about a year, and all of these plants are grown in containers and less than a year old, all by mail order from either Harris or FourWinds. Two of the issues I noticed when I first got the plants, and have been getting progressively worse over the summer. All of the plants are in Miracle Grow Garden soil and perlite mix. I've tried several different fertilizers to see if the micronutrients in any one of them might clear up the issues. But just seems to be getting worse.
#1 Nordmann Kumquat
Yellowing of leaves characteristic of a metal deficiency. Thin darker veins. Newer leaves more pronounced yellow. Plant came discolored, getting worse.
#2 Meiwa Kumquat- (actually 2 plants same issue from same grower)
Yellow spotting, and small brown lesions within spotting. Leaves drop before the leaves turn yellow completely. Plant came discolored, getting worse. Have lost about a third of its leaves. Thought maybe Magnesium deficiency, so treated with 1tsp/gal Epsom salt, but still getting new developing symptom.
#3 Meiwa Kumquat -(different plant different grower)
Lower half of leaf turns a yellow green, then leaf falls. Have lost nearly half the leaves on plant. Some leaves show a puckered effect around the leaf veins. Possible overwatering?
#4 Rangpur Lime
Old leaf bronzing. It almost looks like a sunscald. But the location on the plant wouldnt suggest that. Just a Nitrogen thing?
