Hey guys,
One of our plant seems to be burned and another one has its leaves curling upwards on the sides. Any ideas what have caused this? The problem of the burn could be too much nutes, but we fed them two weeks ago. I thought its ok and by this time everything should be fine, but the burn continues day by day, although very slowly. Please help us out!

Thanks in advance!

Looks like nitrogen burn.

What are you feeding them and how much?

What is your medium? *soil, hydro, coir?

What's your Temps and humidity?

I fed them around 6ml of mixed organic nutes (recommended was 7.5), I'm growing in soil, mixed with perlite.
We recently had fungus gnat problem because of watering too much, so recently we tried watering them only when the top 3 inches of the soil were dry. Don't know the humidity. Temp is always kept at around 70 Fahrenheit.

Definitely not nitrogen burn! Plants look very healthy. That little discoloration, assuming it's not a bug, looks to be something that splashed on the leaf or perhaps it was stuck together to another leaf and the moisture between them left it marked like that. As for the bending of the leaf..usually it bends like that because it's too hot, and/or too dry.

Ok, so now im confused :D i dont remember that something was splashed on them, neither that the leaves of the plant were touching. im suspecting now that this might have happened because of Zn deficiency. can it be?

Hard to say u less you actually explain what your nutes consist of. Other than organic.

How much of what are you adding?

Based on your pic, it's just that one spot on the leaf that is an issue? Nothing else? Zinc deficiency doesn't look like that, plus it starts at the top of the plant. Again, if it is just that one single leaf and everything else looks fine, i wouldn't think it's a nutrient issue.

Nutes: 5%-N; 0.3%-P; 1%-K. also has many microelements: Mg, S, Cu, Cd, Zn, Ti, Mn, Fe, Ni, Co (no indication about quantities tho.) I mixed 6ml (recommended was 7.5ml) of these with 5l of water and watered all three plants.

no, other leaves also have those yellow strains on them. I just posted the most damaged one's. Also this problem is only with one of the plants, others seem to be unaffected or you can barely notice those strains

Honestly im not familiar with those kind of nutes. Plants, to my knowledge do not need or use titanium, cadmium or nickel. I wouldn't even be able to tell you how those unnecessary elements would affect/interact with the ones that are necessary for plant growth.
