The damage on these leaves is textbook <strong>stippling<\/strong> (chlorotic mottling).Unlike edema (which creates raised, crystal-like blisters on the underside of the leaf), stippling almost always points to pests with piercing-sucking mouthparts.<strong>1. Spider Mites (Most Likely Culprit)<\/strong><br \/>\nWhy it fits: They suck the sap out of individual epidermal cells, leaving this exact &#8220;micro-mesh&#8221; or mottled look.<br \/>\nWhy they couldn&#8217;t see them: In the early stages, there is no webbing. The mites (especially eggs and nymphs) are translucent and hide tight against the leaf veins. A cheap 5x or 10x magnifying glass is rarely strong enough to spot them.<strong>2. Thrips<\/strong><br \/>\nThrips also cause stippling, but they usually leave behind tiny black dots (frass\/poop) and larger silvery patches.<\/p>\n<p><strong>3. LED Phototoxicity (Light Burn)<\/strong><br \/>\nIf powerful purple\/pink LEDs (visible in the background) are too close, they can destroy chlorophyll. However, light burn usually creates localized, solid bleached patches in the center of the topmost leaves, not a scattered &#8220;rash&#8221; over the whole plant.<\/p>\n<p><strong>Action Plan:<\/strong><\/p>\n<ul>\n<li><strong>The Paper Test:<\/strong> Hold a crisp white sheet of paper under the leaf and flick the leaf firmly. If tiny, crawling &#8220;dust specks&#8221; (red, yellow, or white) fall onto the paper, you have spider mites.<\/li>\n<li><strong>Isolation:<\/strong> Immediately quarantine the 3 affected eggplants away from the other 9.<\/li>\n<li><strong>Treatment:<\/strong> Standard insecticides <strong>do not work<\/strong> on spider mites! You need a dedicated miticide (acaricide) containing Spinosad, Neem Oil, or horticultural soaps. Ensure you spray the undersides of the leaves thoroughly.<\/li>\n<li><strong>Humidity:<\/strong> Spider mites thrive in the hot, dry air created by central heating and LED lights. Bumping up the ambient humidity slows down their reproductive cycle!<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\ud83d\udccc Quick Summary (TL;DR): Diagnosing Spots on Eggplant Leaves \ud83d\udd26 Light Burn vs. Pests: Many growers mistake tiny white spots on indoor seedlings for LED light burn.
