Can you help me figure out what is wrong with my plants? New grower (pics inside) Thank you!

Gotcha.

I'm noticing a lot of people growing in coco mixes, is it better than soil? Are there more benefits compared to soil?

Better? There's a learning curve for either.
For me, coco is better than soil. I can't deal with not knowing what's in there, how long until it's available to the plant or waiting days to see improvement if there's an issue.
With coco, (I run straight coco btw) I know what goes in, what comes out and how much my plants are feeding and I can adjust as needed. If there's a problem I can correct it overnight (issues appear just as fast though). Slightly more work involved but I like the control I have with coco.

I would like to first of all thank everyone who replied to this thread. I've taken all of your advice into account and I appreciate the time you've taken to help me out.

I will make a more detailed and proper update post later. Life has been busier than usual.

As of now, some of my plants have been showing characteristics that I am finding difficult to diagnose and treat.
The other plants have been doing much better, thanks to the advice that I receive from everyone here and elsewhere.

For purposes I will get into later, I treat some of my plants different from the others.

The below plants are the ones that I am finding difficult to diagnose and fix.

These plants were overfed and dry. They had nutrient burn as attested to by run-off tests.

Here is some relevant history:

January 4, they were flushed but not enough because their run-off tests a while later showed that their PPM/EC was too high for the stage that they were in (Some of them had EC 2.5 or 1750 PPM!)

January 7, one of these plants was given a 600 PPM fertigation and its run-off tested at 1320 PPM!

Therefore, they were flushed more thoroughly on January 7. (I fear that it was a bit too thorough).
They received about two gallons of low Cal-Mag'd (580 PPM) and appropriately pH'd solution each. They are in three gallon containers.


It is now the end of January 13, and this is how many of them appear. I have some other strains in there and they are doing much, much better than the rest.

I gave them a bit of fertigation today at 800-900 PPM with pH 5.8 - 6.0. The pots were looking too dry.

Why are the leaves showing strange characteristics such as edges curling inwards, and heavy droop?

I can understand that the droopiness may be from overwatering. It has been several days now, and the droopiness is still present. I am a bit concerned.

Have you guys seen anything of this sort before? I and I am sure others would love some light on this issue.

Speaking of light, I am beginning to suspect that my lights (LEDs) are a bit too close to the plants. I will provide a more exact measurement tomorrow. Could this be light stress related?

Have an awesome day!
