Leaves with white spots

@WilliamsUrbFarm I suspected about the Mg deficiency as for different green shades on the leaves, but what I found weird is that the white spots appears even in very young plants, but not all leaves have these marks. Here's another image: https://ibb.co/QMx8Zp3 I'm using tap water (should I use a different one?), can't measure the pH right now, got a new tester and its on the way. The soil I use to start has pH 7.

it looks like a calcium and magnesium deficiency, with what kind of water are you watering? and what ph are you working with?

@MangoDudu and @SeseGrows appreciate the help. I couldn't find any insects around the plant, but just did the garlic decoction and will spray it tomorrow just in case. The Mg deficiency I was aware of, got recently the CalMag and started feeding it. My pH tool doesn't seem to be working properly, so I can't measure it now, but will try to reduce the pH as well. Thanks again!

Espero que te sirva! Un saludo!

Hola amigo! A simple puede parecer una plaga. Pero la respuesta está observando las hojas. Por lo que veo, te encuentras en una fase inicial/progresiva de Deficiencia de Magnesio (Mg). Esto puede deberse a la acidez del suelo, en suelos con pH alto, o en riego. Es por eso que la absorción de Ca y Mg se ve afectada. 1. Controla el PH del suelo y del Riego. Asegúrate de que estas midiendo bien, calibra tu medidor de ph. 2. Corrige la deficiencia de Mg con sales de Epson: https://thgrow.com/pt/otros/4912-epsonita-500-gr.html

Some kind of pest, u have to check over the plant, under the leaves or near them some kind of insect, but they can be very tiny! Use neem oil or a home madr garlic decoction as a repellent ✌️🏽💪🏼
