One plant out of 12... How does Everything look?

I am growing in a aeroponics setup using the lucas formula slightly modified and most of my plants I think look good.

One of the 12 in my setup has yellowing leaves which appear to be from a K deficiency... If it makes any difference the plant that is yellowing is the White Rhino

Since they are all pulling from the same reservoir is there anything I should change?

Also, if anyone has any idea about what kind of yield I should expect per plant I'd greatly appreciate it! This is my first grow...

I keep the PH at 5.8 with slight fluctuations but never above 6.1

The room temps do get a little high during the night when I have the lights on. The highest it gets to is 90, but that generally is only for about a 2 hour period once the AC unit can't keep up and the air I'm bringing in starts to warm in the late morning.

They are at about week 5 in flower... I was stupid and didn't even write down the date I switched to flowering, but am not worried about it as I planned on pulling them according to resin color not number of days.

Humidity is at 45%. As mentioned before I'm using Lucas with GH Nutes. I also have started adding a bit of CalMag to the mix over the last several weeks.

Would appreciate any help/advice/comments!

i don't know if gh has a silica or if you have another source of it (such as dyna gro protekt which has an NPK of 0:0:3) but you can use it all through flower if you think this is a k deficiency.

looks like quite a lob of herb ;)

Nute burn

i'm guessing he is pointing out the yellow tips in 1 of the pictures

Aww, yes... I saw those tips too... I cut back on the ppm when I saw it just a little bit, but again that was just one plant showing signs so I didn't want to alter it too much

I'll look into it... I might tone down the N portion of the nutes and up the P and K a bit and see the result.

Thanks! I have no clue about guessing how much they will produce as this is my first time, so I don't know whether to expect an ounce or a pound haha

Ya they look good, I have had different pheno's demand more or less but it's hard to give everyone what they need. I never run different strains in the same res just to many variables to deal with. Best to use the old saying "the needs of the many outweigh the needs of the few"........Spock I believe :)
