I need help

That is oxygen starved roots from over watering. Wilted plants leaves dont fold inward like that, over watered ones do. How would you react if i cut off your ability to breathe? Whoever that guy below me is that said they are under watered is a fuckin idiot that doesn't know anything other than how to try and win free seeds by posting bullshit. Your soil is shit man. Look at it. It looks like your plants are growing in fuckin pound cake. Weed likes fluffy soil with lots of oxygen at the roots and on the dry side of things. Soaked caked soil like yours suffocates the roots and is a breeding ground for the bacteria that causes root rot. Why do people plant seeds with absolutely fuck all for research before they do? I'll never understand that. You have google at your finger tips.....you can gain all the knowledge you need for success........................yet here we are....

The substrate is dry and someone told you it's from overwatering, lol. definitely looks like a bit more nutes needed. Did you increase light recently? this could be too much light... definitely lacking drainage/aretion qualities in your substrate so that could be a contributing factor. watering habits are important, but they are simple.. just in case i'll go over it and compare your behaviour to eliminate it as a cause. first, you want about 50% perlite or similar amendment in soil for good drainage and good o2 penetration for roots. This will make 'overwatering' virtually impossible unless you choose to run a constant stream of water throaugh it for 10+ minutes, lol. Always water so that the entier medium gets wet. Dry pockets are bad. This is also important for how it dries and how roots turn toward the areas of most moisture -- physically built into the growth process and mindless. this way the mostly turn downward as opposed to a greater proportion growing superficially. superficialy roots exposed to light wil turn to stem. compaction will occur so roots at top are likely to get exposed with bad watering habits. So you got the entire thing wet, maybe even a bit of runoff -- not necessary for soil all the time, but a little is okay. Limit runoff when things are agoing well because this simply wasts the nutrient charge that you paid for in that soil. When top 1" deep dries, repeat. Simple as that. when you have a build up of nutes causing toxicities in the plant, a little more runoff can help reduce nutrient content of the soil. fertilization frequency wholey depends on how concentrated you mix it up... whether every other irrigation or every third or once a week... more about personal preference, but you will get better results from more frequent, less concentrated applications.... this is a big reason why soilless/hydro grows are faster, as well as the type of ingredients that are 100% plant useable the moment they are dissolved, which is not the case for all soil nutrients. it's smart to go slow and ramp up.. Much easier to add than try to take away from the medium. Keep up the trial and error... take soem notes about how you are mixing fertilizer each time so you can make a more infromed decision when something does come up. Within a few grows if it's not smooth from seed to harvest, then you can think about a little self-reflection on methods employed and how you went about improving it, because it didnt work :P -- no worries.. i'm sure you'll do fine.

You need to up your base nutes. Definitely needs nit

Your diary doesn't have enough information to really give us a clue what's going on. It says your in soil, if your not using a cannabis friendly soil like biobizz and are using something like miracle grow then that can cause you problems. I can't see any perlite in your soil and that's no good for these kinda plants. The roots need plenty of oxygen and the perlite helps alot. I'd say you may have an overwaterimg problem or your soils at the incorrect ph. If I use 8L pots I only water once every 3 days. If your watering before the top layer of soil is dry then it's bad practice. Get your diaries sorted, what nutes your using, what ph your watering them at will help us.

The main thing to remember is if the leaves are a uniform color that isnt a healthy green its micronutrients (sulfur etc) or general soil conditions (pH).

Looks like overwatering issue. Roots don't have enough available air such as perlite in the substrate.

I see you’ve made a diary, that’s good, but it lacks a lot of information. In order to get the best help and advice I would recommend you to add things like how much feeding- if any, watering, what’s the soil, lighting information, humidity etc. The better the information, the better the help
