this was my 1st thought so i asked co-pilot:

can rootzone salt buildup in cannabis cause water to not rise in plant and cause leaf edges to curl downward

Yes, rootzone salt buildup in cannabis can indeed cause issues with water uptake and lead to symptoms like leaf edges curling downward. When salts accumulate in the root zone, they can create an osmotic imbalance, making it difficult for the plant to absorb water effectively1. This condition is often referred to as nutrient lockout.

To address this issue, it's important to regularly flush the growing medium with pH-balanced water to remove excess salts and restore optimal conditions for nutrient uptake. Monitoring and managing the electrical conductivity (EC) and pH levels in your nutrient solution can also help prevent salt buildup and maintain healthy plant growth.

Thanks FloridaMike. EC levels in my soil is something I haven't checked yet. Will do so. Will flush it if necessary. Should I wait for the soil to be dry for flushing or is it better to do it as soon as possible, even when the soil is still wet?

You don't think there is a perfect plant, do you?) I don't think you have an excess of salts, and what kind then? That's probably the answer. Concentrations can be as low as 6 ec not leading to blockages, but if you yourself say that something is wrong, maybe it is.

if soil dries i would imagine the salts would dry with it, no?
