What els can I say Bro what more information do u need I need help

a side shot of the whole plant would help. along with the nutrients you use, and how much you added and how often. are you using any additives like calmag or aminos or molasses or anything else that goes in there. whats the temp in the room, how far is the light away? what ph do you modify your food and water to? how do you handle drainage? how often you feed or water. you know, the details.

Am not using no calmag or anything like that my ph is at 6-7 using coco a&b and rizz for veg stage I feed them evry 2 days when the pots are dry n light I add 20a & 20b with 40ml of rizz to 10L of water the light is arms lenth from the plants as u can see in the pic the room temp is 24 to 28 and umid is at 49

could it be wind burn from the fan?

also plants like calmag. how often do you feed and how often do you just water? do you run water through to get run off? and what do you do with the run off? do you let it reabsorb into the pot?

there in draining pots dude I don't reuse water that drips off n could it be fan burn I looked at leafs on the other plants n the nowt like this one

If it's isolated to only two leaves then I wouldn't worry too much.

It's cal mag def. You mentioned using non. Start it in your regiment and see what happens.
