Drainage issue
I'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions. My first instinct is lack of drainage, do I need to make some holes, bottom or side?

Ph Issue
I want a Ph of 6.5, but when I check the runoff Ph I get 5.9 or 6.0. I just Ph'd the feed water at 7.0 to get around 6.5 where I want, but the runoff stays around 6.0. Any idea what's causing the Ph not to go up to where I want it at 6.5?

Leaves turning yellow from the bottom up
My older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx Its only on 4 leaves rn

Weird coloured leaves
The leaves are yellow a bit on the outside and just today noticed that it looks kind of black too. Anyone know if this is because of a certain deficiency?
