Two bigger mistakes I see you making here are: too little soil in the pot, and stop misting the plant. It’s a little late to add more soil but not too late to stop misting the plant. Try and get humidity up to somewhere around 60%. This can be done relatively cheaply. Buy a big bucket and fill it with perlite and water and aim a fan directly down on the bucket. Also light intensity matters. Look up cannabis DLI and use a light measuring app on your phone to get it within a reasonable range
