Why are they doing this?

Overall my plants look good I'm just curious why the leaves are turning up(no not getting loud and angry haha). This is only my second time growing and my first time indoor.. I've never used nutes or anything until now.. I'm a pretty fast learner so I've kinda just learned on the fly by myself.. the plant that's further along looks better overall.. any suggestions would be great

They are hungry. When the hit flower they want to be fed higher PK and less N + some Cal mag too. But it sounds like you are using amended soil so it's outta my ball park. Apart from the leaf edges your plants are looking great for a second grow.

Thanks.. yeah I made my own soil with blood meal,kelp meal, Epsom salt,bone meal,earthworm castings, and a few other things. I use foxfarms grow big,big bloom and tiger something but I didn't even have a grow room when I first started now I have a 4x8 room . I need some ventilation but the guy I was gonna get it from(a heating and cooling guy)ran into a little law issue so I can't get it now lol..

To get good feedback provide more info

Feeds /nute regime
Soil/medium
Water source/quality
Light+hum+temps
Co2 amount (even non enriched)

These will all help people see what the control is and potential problems for you. If I had a guess I'd say your medium is no longer buffering pH and you are locked out cause you're growing so rapidly

Oh ok.. I made my own soil with blood meal,kelp meal, earthworm castings,bone meal,Epsom salts,and a few other things I can't remember at the moment but I use bottled water because I have well water that's really high in pH and the bottled water I use is about a 5 in pH. I use fox farms liquid fertilizer big bloom, grow big, and tiger bloom.. every other watering not the grow big tho it's for veg pretty much

Are you referring to how the leaves are Tacoing?
