I think i overwatered somehow what should i do

I think i overwatered i’ve been giving them around 1000 ml of water every three days or so when they’re light , i’ve also been using a water meter stick to check the moisture level in the soil. I always water when it reads dry. Maybe this is a different issue but all my other plants are doing just fine.

Just let it dry out, water less often. Just fyi those moisture/ph soil inserts are useless and very inaccruate imo
