Just a guess, but it looks like a vascular problem, perhaps waterlogged roots, or some root damage. Low humidity and reasonable temperatures should not be a problem.
I'd hesitate to give you a solution, I must admit I'm no expert on soil.

You should read this thread

https://www.rollitup.org/marijuana-plant-problems/150004-plant-moisture-stress-symptoms-solutions.html

they appear to be overwatered and over fed

plus you must be able to control your temp & humidity!

the enviroment you described is not optimum for proper transpiration to take place

yield should be the least of your worries, you need to get that plant healthy or there will be no yield

a solid good grow is the sum of ALL the parts and humidity is one of the parts
