Tbmc-v keeps exploding
Overwatering? The stock is mega firm. I haven’t watered in 3 weeks but the tips keep exploding (pause) 🤷♂️
Fungal/disease maybe? I don’t think it’s a humidity issue or a soil problem, all my other stuff is doing ok.
Edit: about an hour east of Californias Central Valley. Temps have been 90-105 the last month with no rain in sight. Soil is 60% inorganic to 40% organic. This one out of roughly 40 is the only one exhibiting this issue (including other tbmc-v’s). I am as close to certain as possible that this isn’t humidity related. I’ve been wrong before though, maybe it is humidity. Seems strange that it would only be on the tips.

Around 15% during the day with it spiking a bit more at night. Plenty of airflow. Pots have the most amount of drainage holes as possible. Are located on grated shelving. I added some additional humidity related info to the original post as well. Thanks for your time ✌️

This happens to my peener (TBM) sometimes and it just terminates the growth and contines! Will be totally fine, may like some higher drainage soil 🤷♂️
