What does it mean if the newest leaves on a plant have a yellowish cast? And what about the older leaves are slightly yellow closest to the stem? Is this normal or is there a nutrient deficiency?
Normal daytime is 75 (Fahrenheit) and around 60 at night, but the weather has just turned colder so the night temp is probably a bit lower. Tis only a cheap test crop though, I'm just getting the feeling for things before I commit to anything proper.
