Nutrient burn o defficiency? or what is it?

MY SETUP:
600w digital ballast 4d
600w agro bulb+ bulp for vegetation stage.
mylar all around the grow room
4x4 foot grow space
1 FAN, (but as the room is pretty big and well ventilated the room never ever gets hot...thank god ahahha)

i just wanted to know what those markings were, its stained 2 of my bottom leafs, but everything else seems to be green as heaven, i dont know what could have been the cause of it...


if you guys were curious, the bigger plant is a shining silver haze (on day 22) and the others are on day 4, unfortunately i started with 2 plants and one had died so i ordered more and by the time i ordered and they came like a week and a half passed by
and 2 of them are auto flowers xD.
i put them ontop of a box so that they would be the same hight as big momma

STRAINS:
autoflower: auto mazar, pure power plant,jack herrer(outdoor) ak47 (outdoor)
femminised seeds: MOBY, shining silver haze, x2 critical (all indoor)

I believe it's septoria.

(Fungus)

Those two leaves need to removed and thrown away.

I can't say what it is. But I def don't think it's a burn.

WOW wow wow wow, you serious man? i was anyways planning to eventually cut the bottom leaves and give my baby more energy for the top leaves,,, if it is a fungus would cutting them stop the process? as in it seemed to stop, but im not quite sure, i do have doubts, is it okay to cut them at this stage? or too early?

sorry for all the bombarding questions, but you must know as my first grow im pretty anxious xD Been kissing them goodnight everyday hahaha

It comes from rotten matter that's close. It infects plants by proximity. It won't overly hurt the plant just makes it look like hell.

Remedies include removing the infected leaves. For the top soil, I'd spray it with a mix of water, soap, oil, and baking soda..

1 liter water, two drops of dish soap, teaspoon of cooking oil or mineral oil. Pinch of baking soda. Shake it up and wet the top soil. Spray the lower leaves and stem.

thanks allot for the reply, I'll go ahead with the curing of the leaves and I'll keep you updated

seeing that I'm using nutrients too, how much do you reckon I'll end up harvesting ?

what are you using for a soil/medium?@Nicolantonio

biobizz soil..this is the light mix... I use it as it has little nutrients in it so that I can control the quantities. I was expecting like 300grams on avarage but most people ems up with allot less. but my buddy pulled out 500 grams! so I don't know what to excpect

Disagree. It's normal seedling reaction to being put in the soil after an outside pop. The soil can be a bit "Hot" to a new seedling. It's like a "shock" to the seedling. It went from as close to nothing it could get to being in all the food something that small could need.

Points to consider are: No contact with the media. The plant after that growth period has moved beyond the problem and is actually flourishing.
Common seedling reaction to being put in a new media with available nutrition. It was minor and not a real problem to the plant.

I think it's pretty impossible to determine since it's your first go at a plant. I'd recommend simplicity. Get to know what the plant wants. Every harvest will get better than the last.

well said.i had the same problem by using a little happyfrog 5-5-5 in the bottom of my pot.plants had the same exact look.i flushed thinking it was a mild nitro toxicity because everything was so damm green but no "claw" plants lightened up overnight,the spots never spread and plants are doing great now

Is that stem purple?

Basically means nothing......forget about it.

just a quick update, the 2 bottom fan leaves turned yellow and crumpled, so I let them be(I'll cut them today) but mow my top leaves have these yellow markings that look completely different from what happened to the lower leaves... what is that ? nute deficiency? burn or what ?

I'm interested to see what people say. I had a plant do the same thing, I never figured out what was going on. I thought it might have been a iron def, but idk.

Are you staying within 6.5 and 7 PH?
Looks like ph problems

I gguess I was. I always check ph? ranging from 6.5 to 7
I first add the butrient then add the ph compost to regulate it. but I do agree that it could be a ph unbalance or iron deficiency. I hope things get fixed
thanks for the suppor. guys

Burnt as always.

You don't feed baby plants that are already in nutrient rich soil. You burn them up every time. It's not fungus. If it were fungus, you'd see small growths on the soil surface itself which you don't.

yeah, but first of all that plant isnt a baby, its fucking huge now!
even at the time of the pic.
and 2nd i bought this soil specifically because it didnt have rich soil, for the seedlings, so that i could control how much nutrients are in their system.
idk what it was, the plant grew extra layers and they are all fine now, il send you guys pics with updates
