Why are the tips of my leaves turning brown and crispy?
My plant is 3 weeks old and the very tips of the leaves are starting to turn brown/yellow and feel crispy. The rest of the leaf looks green and healthy. What's happening?

Tip burn is the most common issue I see from beginners. It's almost always from feeding too much too early. Cannabis is way more sensitive to overfeeding than underfeeding. When in doubt, feed less.

Check your runoff EC/PPM too. If it's significantly higher than your input, there's salt buildup in the soil. A gentle flush with pH'd water can reset things.

That's classic nutrient burn — the tips burning first. If you're feeding nutrients, cut the dose in half. If you're in hot soil (like FFOF), the soil itself might be a bit strong for your seedling.
Just water with plain pH'd water for the next week. The burnt tips won't recover but new growth will be fine.
