what are you using for a medium again?

Its just jiffy seedling mix .. its very hard to saturate initially gt mix it by hand to get it to do that.. i recently flushed.. then i poked holes around rim with a pencil fora bit more air penetration too.. it has no nutrients soo i used fertilizer.. soo its why I was on the fence about either nute burn or overwatering.. rough when cant tell difference and the solution to one involves making the other worse lol

what is your budget? Where do you live?

I started with Ebb N Flo Hydro outdoors...
Then tried DWC indoors but it was too much work to keep it going...

Then I switched to coco with perlite and some hydroton (had hydroton laying around from past hydro grows) and used General Hydroponics General Organics nute line with a moderate amount of success...

But honestly I just got back into growing after about 10 years of not growing. But before that I grew for close to 11 years.

Now I am running roots organic soil, perlite and a mix of Nature's Living Soil Auto Mix and all i have to do is water my plants... the only thing I pH is my water. My mix is completely organic and the plants take up what they need when they need it... unless there's a problem there is no guessing... the soil is living so it feeds the plant everything it needs.

Everything can be bought online.

Roots organic soil (10 gal) - $42
Natures Living Soil Auto Mix (5 gal) - $42
Perlite

Also use something to elevate your pot or bucket above a drip pan to catch your run off and make sure the bucket or pot isn't sitting in the run off in the drip pan... it will cause root rot, root fungus, fungus gnats and nutrient lockout...

If you feel you have nutrient burn with what you are currently running then you may be able to flush the soil completely and let it run off until it completely drains out leaving only moist soil... dont water again until the first inch or two of soil begins to completely dry out.

When your plant is overwatered it droops... when your plant is fed the correct amount of water or nutes then the leaves will point upward towards the lights

Also how close is your light setup to the top of the canopy?
It kinda looks like some of your leaf tips are light burned a tiny bit but not a big deal at all right now...
Correct the watering issue first then maybe raise the HPS and LED to about 24 inches above the canopy for now
