I really need some help diagnosing my plant.

Hi, my plant has been having some issues lately, please help me understand what the problem is. I will attach pictures below.

Information :

Tent size : 60cm-60cm-160cm
2 smaller intake fans and 1 larger outtake fan. ( I couldn't post the second intake fan pic, but it is located near the ground and the one I posted pic for is higher in the tent)
Strain : zkittlez OG auto
Age : 29 days
Light : 600W LED grow light
RH : 52-55% at day, hits around 58-60 at night
Temperature 23-24.5 day / 18-21 night
Pot size: 10L
Medium : Soil
Nutrients : Advanced nutrients - 2.5ml micro 2.5 ml grow 1.5 ml bloom | General Hydrophonics 1ml armor si , 1ml cal mag. All this mixed in 3L tap water. water PH 6.3-6.5.

Feeding method : Watering with 1L. Nutes > plain PH'd tap water > Nutes > plain PH'd tap water and so on.

I have another plant right next to it which has 0 issues so far and is overall growing much better, the other plan is in 20L pot and I pour 1.5L water per watering on it, they both get exactly the same nutes.

Here are pics :

Looks like you got the nute water on the leaves and it burned them

That's really weird, I lift them up with my hand each time so that water doesn't touch it, I did burn the lowest leaf the first time I watered it, it's on top fan leaf now.

Also I would like to add, on other strain, flowers are much longer and they touched nute water much more, I just dry them with my hand and no signs of any burns whatsoever.

Giving two plants the exact same feed may cause issues
It looks a little Nitrogen heavy unless you are growing under a blurple

I try to do the same thing but I have the same spots on my lower leaves so I hope its just the water and we don't both have a problem lol

At first I had them under blue, now it's both veg and bloom for last 3 days. The first spot appeared around day 17ish. I was gradually increasing nutes, started with 0.4ml/l micro/grow and 0.2ml/l bloom and I went with half as much bloom each time I watered with nutes, I increased bloom dosage for first time today. Last week I was just giving them 2ml micro/grow and 1 bloom mixed in 3L

What is the brand of your soil?

I hope he doesn't say FF anything

I’m assuming he’s giving nutrients too early before the soil is depleted. But I could be wrong

That might be the issue, I water every 2-3 days, and soil is slightly moist each time. It is not completely dry, I do it because my plants get really droopy and when I water they spring to life right away.

Please be more specific. When you say “water” every 2-3 days are you giving nutrients also?

I do Water > nutes > water > nutes.

Also my medium says : it's a mix of coco, bio mix, perlite, Peat substrate, Perlite. N - 1.0, P2O2 - 2.0 K2O - 2.0. That's what's written on the container.

I've posted about this issue around 2 weeks ago and turns out you commented the last time as well,
