Root bound

I know it is rootbound. And it is rootbound in a 7 gallon container. So I cut the bottom off of that pot, bought a bigger one, put dirt in the bottom of that and set the plant on top of that. It shouldn't need nitrogen, she's flowering, she needs phosphorous. All nitogen does is turn the leaves green. I aint smokin the leaves.lol. Well she only has 20 more days. Hey it's my first grow. I am definitely learning. I got 2 seedlings I germinated "Orange Crush", One 11 days old that is close to topping and the other 2 days old. I have 2 grow rooms. My veg room is 250wh. You know I have to say I got no help from the RIU community in figuring out what was wrong. It's nitro, it's nitro. One thing is, you don't always have to fix your plant. The plant knows she close to the end so she is using all her resources. If u notice none of the leaves are curling, so it's not a burn or lack of.

Use smartpots instead of plastic pots and she wont get rootbound at all! Though some strains yellow from the bottom up not just from rootbound issues but through genetics.
They will shed their foliage no matter what you do while others keep em green to the end. This is a process of using available energy from the leaves to focus on bud growth. Ive only seen 1 strain that does this to the point of losing ALL leaves and another that just yellows the foliage late into flowering. Id say strains that purple are more likely to do this.
Keep it up man. Looks like some nice nuggets ^_^

Yes its rootbound but not too stressed, keep up the water/food.
