Oh I like this one, nice find. Its harder to determine an "artists idea" of actual effects on the leaf, than it is real life examples of it. Thank you for this, it will definitely come in handy.

Thanks. This is a good one. I've used one like this for years.

Good. Can we finally get a sticky telling people to stop calling everything light/heat/nute burn?

I don't think it's that simple. Light, water, and nutes operate in a balance. The light is the accelerator, the nutes in the pot are the gas tank, and watering controls the flow. Too much light creates nutrient deficiency symptoms. Too much salt in the pot draws water out of the plant. Over-watering impairs nutrient uptake. Seeing symptoms of a particular elemental deficiency does not necessarily mean there isn't enough of that element in the pot. It might, but it also might mean that light or water are out of balance. That's where the nute death spiral comes from. You feed properly, but over-water. The root hairs drown, and you start seeing "deficiencies." You put more salt in the pot to correct it, and you can end up drawing water out of the plant and making the leaf symptoms worse.

Many if not most symptoms and indicators can have multiple causes. Of those, there are usually a few causes that are more common. So, the pragmatic approach to solving problems is to address the most common and thus the most likely symptoms before addressing the least common and least likely. Among the most common issues is in fact light stress or light burn. Those of us who grow under artificial light eventually know this from experience.

Thanks. This will definitely help me out. I'm bad at distinguishing deficiencies.
