Possible Nutrient Burn, Input needed Please.

Hey guys,
So one of my girls is not doing so well. She is about four weeks old and shes outside. I grew her from seed, not clone and I feed her about once a week. She's being fed with a compost tea that I make. It's just a simple seedling tea, with only earthworm castings and unsulfured molasses. I usually mix a little less then 1/4 cup of tea in 2 gallons of aerated water and feed them as needed. I noticed about 2 days ago that she was starting to curl at the tips of her shade leaves and now they are turning black. I also sprayed her with diluted Neem oil about 4 or 5 days ago, as kind of a preventative because I have had mite problems in the past. I flushed her with pure water yesterday as well. So I figure, its either a nutrient burn, or it's burns from the water droplets that the Neem spraying might of left over on the shade leaves. I'm not sure, but any input would be much appreciated. Here are some pics of her, and I'm gonna go get a PH tester and test her PH today.View attachment 2046902View attachment 2046904View attachment 2046907

were those leaves in contact with the soil? when you water do you spray the leaves that got splashed afterwards with clean water? Please post every detail of your grow and a picture of the whole plant

Thanks for the reply maps. Those leaves weren't really in contact with soil, but there has been 40mph gusts here where I live. I think it kicked up a lot of dust and dirt and it stuck to the leaves via the Neem oil mixture, but no I don't spray down the leaves that get splashed when I water them. Is that something that I should be doing? Anyway I tested the PH of the soil and it's at 7. I'm using 18 gallon plastic pots, with a locally made organic soil mix. I feed them nutrients once a week usually, and I give them water about every other day to every couple days, it depends on how dry the soil is. Here are some full shots of the plant in question.

They look excellent mate, if there was a problem it's fixed by now so nothing to worry about

By the kill the plants growing next to your cannabis in picture 3, they could turn your plant male

Thank you maps! I've been stressing all day about it, but I feel better now. Those little plants are french marigolds. I read somewhere that they keep certain pests and nematodes away, but if they're gonna stress her out then I'm gonna pull them.

I didn't know they were beneficial neither if it's a safe practice. Maybe wait for another opinion on that
