Help with unhappy plant

root rot ? watering every day wrong tactics in soil you have to do wet/dry cycle. such girl needs good soaking, but at same time ley her consume all moist, lift by hand pot, you will feel when its light, then only you water. you could heavily change ph of pot too, by keeping it moist all time, roots needs oxygen, in soil leting them dry out allows them to get it.

Do what autoflowers suck said.

Good answers below: Don't forget given they are an autoflower watch how much feed your giving. normally HF and OF is to hot to grow autos. Less is more in this case as you can't get good runoff without supersaturating the medium. Good Luck!

Over watered. Root Rot. 2L every 3 days in heavy soils like happy frog and ocean forest. Even with perlite that's still too much water man. That soil is gonna be water logged. It's got sticks of wood and shit in it that will soak up water. Only water your plant when the pot feels light when you pick it up. You have to water your plants when they need it, not by a schedule. Your pH needs to be adjusted as well. 6.3 ideally in that soil. You got big problems there man your roots are in trouble. You need a Cellulase enzyme to be watered in to attack and dissolve the dead and rotten root matter. Otherwise that plant will die. Root rot spreads and will take out your plant. Hygrozyme is what i use, but there are other brands you can try like Advanced Nutrients Sensizyme. Just about every nutrient manufacturer has their own version. Better get on it quick.

Wow erm this is a tricky one ? What are your tempertures drooping leaves tend to indicate an overwatering issue but i think there is something larger here at play. it does not look like an overfeed. Have you looked at the feed table that comes with your nutrients ? maybe the 1/3 in nutrients isnt doing her anygood i cant see it being a root problem as your using fabric pots so roots should have enough air. the brown spots make me think she needs more cal mag in my opinion :) best of luck buddy
