This plant did not have an easy life, I had a major issue when starting. The plant shot up right away, as normal, when it was about 4 foot tall, it started dying. I read up on it and the leaves could have been turning brown from not enough water, or too much water or not enough nutrients, or too much nutrients...
So, I went out and stuck my finger in the dirt to see if it's dry, and when I pulled my finger out, my hand was covered in ants. I moved the wood-chips away from the dirt to see billions of ants, billions. They had dug a hole in my root system and were probably eating the roots.
That day I put a good layer of
diatomaceous earth on the top, then mixed it into the first few inches of dirt and 2 days later all the ants were all dead (free fertilizer).
At this point, the main stalk was dead, I had to cut it, so now all I have are the side branches and they were a little bit stunted in their growth, but they did come back pretty well.
A few weeks later the leaves started turning brown again... I figured it was water, too much or too little, so I took a chance that a gallon or 2 a day wasn't enough. The plant is in a large pot (about 3' tall and 2.5' wide) with holes in the bottom so water can escape and worms & bugs can work their way up from the ground. So I started giving it 4 gallons every other day and it came to life. That's a lot of water for a potted plant. Even when it rains I still need to keep watering, I guess the leaves from the plant cause the water to drop outside the pot, so it doesn't get much water from rain. I'm going to set up a rain recovery system on our house next spring so I can use 100% rain water.
20+ years ago I grew indoors and there were times I cut the main stalk just to get better buds on the branches. Someone from Michigan State University was giving away clones of G-13 for years, so from around the late 80's through the 90's I had good weed thanks to those G-13 clones. I only grew from seeds one time, it was a sativa and it took up almost my whole grow space, the thing must have been like 7 feet (in my closet) tall while all my indaca's were around 3 feet tall. Because it was so tall, I had to train it, the plant went all the way around my garden with the indaca's in the middle.
