With your soil and the amount and how you water , I believe your soil moisture content may be a issue , give it about 50 mls of water around the plant . What will help if you can scrape some dirt down a inch or so and see how damp the soil is . I am leaning towards the soil being to dry .
Amount of perlite in the picture is a bit misleading....Perlite bag came a few days late, so only top 1/4th of fabric pot is perlite mixed with soil....bottom 3/4th is just straight soil lol....
I put my finger in and its still slightly damp about a fingers length down. Should I water more?
