Thanks in advance for taking a look at this. I'm a first time grower. I have a plant that is starting to show signs of some kind of deficiency, and I need some help identifying the problem. There are currently 2 leaves that look like the most severe picture ( the one on the left). These leaves are at the bottom of the plant.
There are another 2 leaves that look like the less severe picture (the one on the right). These are located just a little higher on the plant than the more severe ones. All the leaves that are higher on the plant than these still look fine, so hopefully I have time to do something.
Here are the details regarding how this plant has been grown. Thanks again for any help!
