Please help diagnose the problem

This is my 38 days old. Today when I re-planted it into a larger pot I noticed the de-coloration spots on the leafs. And as you can see, the plant is kind a ...dropped...

The soil is mixed with nutrients.
Light 18/6 on 4 DL x 35w (6400k each), pH is about 7.3
To add...I had a bug problem, gnats. I tried to water less the plant to get the visitors out naturally.
Please help to diagnose and manage the problem

It could be it needs more nutes but I don't know
what dirt and nutes you have already gave it~
The drooping may just be from the transplant and
watering you just done.

it's a pre- fertilized soil ; they are saying it doesn't need any nutrients for at least 8 weeks

might be cause lately I tried to give less water to it to dry the soil for thous gnats to die and that can be the reason for the drop. I don't know, that's why I am asking the forum...as per the spots...no idea...heat stress?Gnat eating place? I don't know... Please help.

Just a guess...are you misting the plant? If so those are likely water spots. About the gnats...get a bag of playground sand and put about an inch thick layer on top of the soil. Also the ph is high get some ph down or try some baking soda.

no...I am not misting the plant. I've searched in the local garden stores for sand or gnat killers but with no luck. Baking soda I have...how much should I add in what quantity of water?

Ive had it happen to me when i transplanted before ,.just make sure to give plenty of h20 and that yur soil is well aerated.

Don't really know to be honest I never had the issue mself. I am sure there is some info on it somewhere on the forum though.

i agree with what he said.

I recommend against baking soda ... sodium is not good for Cannabis plants. cn

it looks over watered mate, put a jar of vinegar open in your box, gnats love it and commit suicide in it.

Some more pics and much clear...please advice, I am getting worried

How hot is your box? at first sight in the beginning I would say it was growing in stomata and the leaf itself but... maybe you should get some fulvic acid or superthrive. get an eye-dropper and plop one drop of b12 in a gallon of water. or 1 tblsp. of fulvic in a gallon of water. b12 helps aid in disease resistance and makes them pretty tough. but also suggest as I did earlier in a previous one. air pumps or small air stones the tiny round ones! are ideal to put in a gallon jug of water and let it bubble until you water. just make sure you shake the jug up real good when you take the hose out to prevent unsettled nutes from staying in the bottom. idk bro that is a tough problem you got there im not real sure but I suggest using some b12 just my 0.02

When it comes to knats... they fucking suck ! stop watereing until the top os bone dry and shit crusty! scratch up the top of the soil and insert some sticky traps in your box. your gonna have some regardless but this is usually do to dirt being outside or where it stored or definately extra water and moisture. I suggest again letting it dry out good and scratching them bastards out of your dirt and the use of sticky traps or the fly traps that you pull out of the cylinder and comes in a 4 pack with the wax plug and a thumbtack you see people hangup in carports!

Ph 7.3 at its highest 6.8 ideally 6.5, it looks tobe p def also my def ph your water and flush that girl

Mag def not my def lol sorry for db post cant edit

the soil that I am using is pre-fertilized, I've noticed the changes only at day 36-37. It's only on about 3 leaves from the bottom. The rest of it looks healthy and well
