In this article, I will share how we were able to remedy a case of cannabis root rot in a hydroponic setup. Root rot is often thought of as being "incurable" and I've heard of several cases where growers throw away their cannabis plants that are hit by root rot. I know lots of growers who have tried hydroponic growing, and gave up after running into root rot for the first time.

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.

Spider mites (sometimes called spidermites) are part of the mite family and are related to ticks and other mites. They're a common cannabis pest, and can be hard to get rid of.

Question: My first bottom leaves have died and the tips on 3 of my 12 plants have started turning yellow. This is my first grow.

Here's a picture showing the damage on one of the marijuana plants:

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...
