How much is slightly cold, because temp can cause discoloration. Looks like she needs nitrogen. Worm castings will help, but it may need something more. Give it half and half veg and bloom next feed if the worm castings don't green it up over the next few days.

What week of flower are they? They will naturally fade at the end of flower. They might be a little hungry but I wouldn’t go feeding a bunch of Nitrogen

I’ve been running a 400 watt hps. was running at 75 degrees with lights on. Last couple weeks with light on was 73 degrees and lights off anywhere from about 62 to 65 degrees. Flipped to flower when it was small because I am looking for keepers. More than likely this won’t make the cut. Anyway this just finished week 11. In House Genetics Flap Jack

Looks like normal fade, most in house strains fade like that.
Look at the stems, if they are fully green then it's probably not a def.
Yours look a bit light purple with green which means you can probably push more P and K but it's looks like your on the edge of overfeeding so choose your feeding carefully (what you put in terms of what elements and how much)
Also, why are you growing in 74f ?
Are you trying to grow ice cubes or plants ?
Temps in grow should be 80+ for elements to move properly within the plant.

I am in an unheated space and it’s winter time so a small radiator and the hps are the heat.

Move the lights closer, make sure canopy don't fall under 26-28c, keep in mind that if your canopy is 22-24c, below it is even more colder.
So try to keep temps optimal.

Most def N, and a bit of P.

If you look at some of the colas, there is dark waxy green leaves right below the yellowed tops. Doesn't that seem less like N? And my bloom feed should be hitting p but I could top dress or pore in some p heavy ammendments

Yes it looks like your over feeding already like I said above, try adjusting ph to 6.2-6.4
And lower your ec but make sure what remains of your ec is mostly npk
Don't stress too much as fade also plays a factor and can mislead sometimes
slowly but surely lower your ec.

Don’t change anything, that yellowing is probably cause you were a little low on nitrogen during the first couple weeks of changing to flower. The need for nitrogen will taper off a little and your worm castings and bloom feed should cover it. The dude telling to raise the temps doesn’t realize you’re using hps i think. A degree or two higher wouldn’t hurt but I wouldn’t think your temps are causing any problems. I try to do a past present future analysis when I’m trying to figure shit out. The plant is always changing and trying to correct a phase that has passed could fuck up a phase that is coming up. And lots of times thats what we do.
Are you replying to the op or the guy that jumped in to talk about his grow?

lol no I was just posting to the op that the color change can happen with the temps he is running. Wasn’t jumping in to talk about my grow.
