Hello, I have an indoor autoflower grow going on in coco and one of my plants has developed some yellow blotchiness on the lower leaves. I know I did over feed it once, but im not sure if this is the cause. I The temps are from 70-75f and I can only get humidity up to 50%. Any help would be appreciated.

Have you checked your ph? Could be causing those purple stems and possible nutrient lock out.
Since it's coco I have to ask - are you giving any calmag? If not, it's time.
 
Yeah I have been giving CalMag with almost all of my feedings. I keep my ph between 5.5 and 6 when I water but you think I should test my soil ph? Do you have any way you would recommend I do that?

From what I know, my experience is limited, you should be testing your run off water. I am growing in coco and try for 20% run off when fertigating. I than check the run off water. Take a look at this article which has some great information on checking values of your run off. Good luck.
