Here's a series of pictures of a couple marijuana clones I had a few years ago.

I was experimenting with growing an entire plant from clone to harvest in a solo cup, which is why you can see flowering plants in such small containers. Each of these were flowered as soon as the clones took root. This technique is often called "Flowering from seed" or "12-12 from seed" and just means that you force the plant to start flowering at a very young age. I wanted to see how small I could get flowering plants.

Question: What do I do if the edges of my leaves are curling up?

Take a look

Question: Why did my plant stop growing? The tops of my plants are curling, wilting, and looking rough around the edges...

Question: Why is my whole plant wilting, curling, with tips turning black and leaves turning yellow? Just flipped to flowering stage. Plant is drinking less than normal.

Question: Why are my hydroponic marijuana seedlings getting tall and dying?

I hear this question all the time...

If you're growing marijuana in soil or another growing medium like coco coir, you will have to hand-water your plants.

But how often do you water?

Well, you will want to water your marijuana whenever the top of the soil or growing medium starts to feel dry. I like to water when the medium feel dry up to my first knuckle, or about an inch.
