There is a jar on the window sill between the plants with water - use the ~80% of the jar, in the following ratio, on Wednesdays, if you are here:
Climber: 40%
Aloe / Zeze / palm: 10% each
The Zeze plant (bigger one) is nigh indestructible so you can skip it if the soil is still wet from humidity.
Refill the jar after 4 waterings.
