hey there Vie, you're right that it's a problem, this is due to overwatering, basically the soil keeps humidity for longer, probably what happened is that the corner plant is a bit cooler, has less wind, etc than the others, so when you water it the same it's actually not fully dry. try pointing a fan or fixing the airflow, maybe wait a few days before you water it. try to keep a seperate watering schedule for this one because it can be a problem if it goes on too long. The good news is that it could fix itself , but just to make sure try to use something like humic acid, enzymes, or beneficial bacteria like bacilus subtilis to break up the problem roots.

Hi there, It’s looked like Calcium deficiency to me.But I can’t tell you exactly.I don’t know what kind of nutrient you are using and There could be alot of factors causing the problems.Deficiency sometimes doesn’t result from lack of nutrient.It may lockout due to improper pH or abundant of other nutrient in that pH.Find out the base cause. As long as you are giving the perfect growing conditions and feeding, they will not go worse.Before you do anything, make sure your water pH, ppm(EC) and run off are in corrected range.Keep your temp and RH in proper range which I prefer around 25C and 50% for all stages.Slightly different between day and night.In that way, you don’t need to worry much about your plants.If you are growing in soil, keep your pH around 6.0~6.5 for both of your water and run off.Also in soil,the less nutrient the better to prevent lockout.Happy Growing... ✌️
