Pueden ser quemaduras debido a una alta cantidad de luz, calor o quizá provocado por aplicaciones foliares. Te recomiendo separar las lamparas usar una EC de 800-900 y un pH de 6.2.

Hi all! I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)

Yellowing leaves and yesterday curl down leaves after watering
I'm growing in coco. Is 500ml/2 days too short watering? Last growth happened the same with lower leaves (yellowing). It was because of nitrogen deficiency. But EC go to much up if I add more fert. I'm at 5.7 pH and 1.2 EC, 25-26°C and 65% RH now. That's why I use worm humus.

Leaves discolouration
I have noticed that a couple of leaves on 2 of the plants are getting yellow spots, the only thing I’ve done differently was that I gave the only plain water without nutrients for 2 days, anyone knows what could it be ? Thanks

Leaf tips browned. What nutrient problem is this?
Leaf tips browned. And some signs of burn/discoloration at the leaf side edges. Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem... Or Potassium deficit? Or any other secondary nutrient deficit?

Should I worry?
A couple days after flipping to 12/12… I see yellow edges to new leaves. Should I worry? Wait a bit and see? The other plant looks fine and they’re both getting same nutes.
