Autoflowering Lemon Skunk, started flowering about a week ago. One leaf set is yellowing to the point of concern, as showed in the image below. I've been using Big Bloom at 1/4 strength, two waterings so far, one spraying of leaves (followed the next day by spraying with plain water). Any ideas what's going on? Is it just an unnecessary leaf set or is there a nute issue? (note, only the bottom leaf is yellow, the upper one looks weird due to lighting) ^somewhat better view of computer case it's growing in. There's a plate of glass between the plant and the lights allowing it to get within centimeters from the lights but stay cool.
its a mobile deficiency, the new leaves and buds are hungry and pulling nitrogen from the older bottom sets, its not bad yet just up ur bloom food, and give it a little time, there small ppm should be around 400-500 once the buds get bigger, the roots will get a lot bigger so ur gonna have to up the feeding a little more good luck
