Yellowing leaves with brown spots moving up the plant

[Newguy36]

Alright guys. New to the forum and new to growing.

this is my first plant and have made it fairly successfully to the flower stage. My plant is in a 2.5x2.5x5.75foot tent in fabric 5 gallon pot in pro mix mixed with perlite. I found this seed and germinated it from some weed I bought from ocs.

the plant is about 3.5 feet tall and is starting to get yellow leaves near the bottom and brown spots on them. This issue seems to be moving up the plant quite rapidly.

I have not used any nutrients whatsoever and have been giving it water ph’d at 6.5.

please help.

thanks In advance.

First off, welcome. Second, we really need pics in normal lighting or we cant see whats really happening with the plant. Third, you need to read https://www.growweedeasy.com/basics. What pro mix are you using? Does it have any nutrients? Even if it did flowering requires nutes. I cant see anything in that light but im pretty sure your plant is deficient. . Check out https://www.growweedeasy.com/nutrients and get some nutes in her. It may be too late but honestly i cant tell in blurple lighting.

Thanks for your response.

here are some pics ive brought it out to give it nutrients which I just bought today as I suspected it was the issue.

thanks for the links. I’ve read the first link but it was my first time reading the second.

Thanks for uploading the new pics! It really helps us see the colors of the leaves. By your pics i can see several deficiencies but you said you got her some nutes so thats good. It doesnt look hopeless, but has your plant is awfully tall. I hope she has finished her stretch. If you feed her she should bounce back but you may want to think about plant training https://www.growweedeasy.com/cannabis-plant-training . Really plant training should have already been done but if you want to maximize your yield you may want to remove everything too far away from the light https://www.growweedeasy.com/lollipopping-cannabis-tutorial

There is a lot of stuff to learn on this website and i suggest looking over as much as you can. A lot of things are better explained there than i could do.

Looks like it could be a issue with the amount of light the bottom is getting, pluck those yellow leave out they should come off easy.
how tall is the plant?
what the actual watts of the light?

It’s 4 feet tall and 300 watt full spectrum led. It’s actually a phosphorus deficiencie problem.
