Beginner- Can anyone help me save her?

[chloec]

hi! looking for any help/advice on why she's yellowing on the tips/the first set of leaves after the cotyledons are completely dried up and yellow.
Here's my set up
growing material: 70% sphagnum peat moss 30% perlite. Update: I just read on the bad of perlite that its been sprayed with plant food already- could this be the source of my yellowing plants?
nutes: green gaia 4-4-4. I added 2 tsp to top layer of soil on week 4 of growing and followed instructions and she started yellowing about 5 days later- was it too much?
Water: I've been trying to follow watering guides, making sure the top layer is dried out but I may have over watered.
She is an orange dream tangerine autoflower and is growing in a 3 gallon pot under a relatively cheap grow light that says its 1000W and I have it at 35% about 18-20in away from my plant.
That's about all the information I have. Would be very grateful for any tips/advice. Thanks!

Nitrogen deficiency
Soil ph imbalance. If your soil pH is off — say, too high (>7) or too low (<6) — the roots can’t take up nitrogen, iron, or magnesium properly. That gives this same lightening/yellowing look..
Overwatering / root oxygen deprivation
The soil looks heavy on perlite (which is great), but if you’ve been keeping it too moist, the roots might not be breathing. That stunts uptake
Chlorine or chloramine in water
If you’re using straight tap water, the chlorine can knock down beneficial microbes and stall nutrient cycling — especially in “super soil”If that’s the case, dechlorinate your water by letting it sit out 24 hours or using a drop of ascorbic acid (vitamin C). Bubble it too.

Agreed, the lady looks like she doesn't have enough N, or not absorbing it correctly due to pH.

thanks for your response! i haven’t been doing anything to my water just using tap . I just got testing strips and my water is about 7 pH. For peat moss I read it’s about 6-6.5, how would I go about lowering the pH of my water?

I just use ph down but I believe lemon juice does if you are growing organically. My ph is super high out of the tap. Like 8.5 to 9. Hope that helps.

This is how Mother Nature trolls those of us who fuss too much over our baby plants.

The composition you are using has no pH buffers. I would recommend using the gia green in a good quality potting soil. pH will change as the soil gets warm and wet from nutrition conversion. Have to get them ions from someplace.
Wet feet from over watering may have turned the bottom of the pot but I do not think the roots are even that deep.
The plant is way behind and you should be talking about flipping to flower instead of the tiny growth you have. I do not think you will amend the soil from this position.
If the perlite with nutes is that green bag miracle grow I do not think so. It is .01 .01 .01 on the bag and that's almost nothing.
Can try a repot into a nice fabric pot but prolly dead.

I forgot to mention, I added dolomite lime to neutralize ph when I first made my soil medium. Do you have recommendations for a good potting soil?

The number one killer of these plants is we love them to death.

If you're looking for a good potting soil, Recipe 420 is a great off the shelf product. DIY carries it. Alternatively, EB Stone is also good.

Any pre charged organic soil that has a good Humic Acid component. Things like Fox Farms organic potting soil and a good one will have a pretty good load of perlite but you will want more for drainage. Shoot for 20% by volume for the pot and mix very well. Lots of growers use Dr earth organic potting soil and the organic nutrients. How simple is that at week 3, 5, 8 and to- harvest literally sprinkle on like hot pepper flakes and add water. Plenty of feed charts for cannabis for almost all nutrient providers ya just hafta dig em up.

Lemon juice works in a pinch. lemon juice is unstable and water will pH back quicklyespecially in the soil. So listen, if you’re using strictly tapwater, what I would suggest you do is get it into a bucket with a bubbler. Bubble that water for 24 hours this will remove all your chlorine. Chlorine is dangerous in high amounts for plants and wrecks any kind of living soil situation. If you’re mixing any kind of nutrients, watch your pH fluctuate between them and see which ones you can mix to properly pH it without using anything. Personally, I use an RO filtration system (just one of them standard little hundred dollar ones) and it works, and then run that through a remineral filter to give my water back some of the minerals I have stripped. a side bit: ( RO water comes out at 6.4 if the filtration is working properly) this is perfect for seedlings even though they don’t really need pHed water. they just need a little bit of moisture and a humid environment to pop. And that’s all they need for like a week/2 weeks

This way of growing is very friendly, set it and forget it. I use the GG 444 @ 3Tbsp per gallon of medium, peat is good, I use coco with 25% perlite. I also add about twice the amount of earth worm castings to the mix as I did the 444. I use tap water without chlorine and add some microbes to boost things. I usually water daily to keep the soil moist, not too wet, which allows the organic magic to happen. She seems underfed in my opinion.
