I don't know what's happening!!!

This plant has started getting brown spots and is looking extremely sickly. My other 4 are doing very good, but this one has stopped getting vertical growth and dropping, and the spots. I fed them a few days ago, so maybe she'll bounce back? I hope so they're doing so well, all of my errors taken into consideration. Some help/ diagnosis would be awesome. Thanks

Do you ever foliar feed your plants or did when those damaged leaves were young? Looks more like water damage from wet leaves being exposed to grow lights than any kind of deficiency or excess of nutes. All the other growth looks great so don't go messing things up by throwing stuff at the plant it probably doesn't need.

What is happening up top with newer growth is more important than a few crappy old fan leaves that could be removed but are still healthy enough to process light and benefit the plant so don't need to be removed. If it was low on N-P-K or Mg those old leaves would be yellowing or getting blotches on them as the plant steals the nutes from them to use up top. Go easy on the N as too much N retards flowering.

I used a mic of half 2-8-4 and 4-8-4 that few yeti well identical. I just fed a few days ago, so I'm thinking it'll get a bit better in a few days from now. But I did speak some water on it when I was watering the last time.

Whats your watering like looks like beginning of root problems to me

My first thought. Consider the pH of your feeds as well. I’m not a pH freak but some strains are more sensitive than others to pH.

I'm saying a ph problem. Maybe fed with very alkaline or acidic feed and threw off ph. It's some sort of ph problem one way or the other

So I was almost thinking roots. So I transplanted them about a month ago, and they weren't filling the pot, but very close. When I fed, I was able to dig down pretty far around the root ball from the 1 gallon of. But it almost doesn't seem to be expanding the roots. That was about 3 eyes ago. What can I do to try to stimulate the roots shooting or more?I've got plenty of room in the 5 gallon t I would think. Now I'm worried

I'm guessing you were top dressing, is that correct?

And next time transplant before flipping. They stop focusing on roots so much when the start focusing on budding.
