Sweet ZZ + Sweet Gelato Auto indoor

i got a thermometer and it is too hot and the humidity is only 33% i need to get a humidifier the Sweet ZZ is in flower now for some reason the leaves on both plants are getting yellow marks on them i cut off the leaves worst effected incase its a disease i'm hoping the yellowing was only caused by the conditions they are in i'm getting a humidifier tomorrow which should bring the temp down a bit and increase the humidity which is perfect Day 36 update i got a humidifier it has made the environment much better for the plants Day 28 update i began some plant bending and low stress training on the sweet gelato to improve the canopy
