7 Days Since 12/12 Switch

Just my opinion, but when I have anything over 240w LED, I keep the power down just a bit, it's more efficient (apparently they say) and I think may be contributing to your issue. I had a SF2000 I forgot to dim once in flower and every plant was green and loving life except this one, I couldn't figure out why. Swore up and down it was improper feeding etc, but something simple as dimming 20% fixed my issue.

This is speculation of course, your problem may actually be nutrient or pH related, but it's best to start at a simple step, see if you get improvement, etc.

I'll definitely take that into consideration. I think it would be strange if that was the issue though, as the intensity has been set at 100% during all of flower, and they've been this close to the light for weeks now--I don't know why all of a sudden there would be yellowing beginning. I'm thinking more along the lines of maybe I've been pushing their Bloom nute too hard, or adding 2 ml/gal of The Rock Resinator may be pushing the P&K too hard

Keep in mind, 100% light means the plant will want MORE food. The more light you give them, the more of the three elements you need. Get my drift?

I get the yellow tips on that paler colored plant lately. I get the purple stems and veins on the "greener" plant next to it.
The longer I think about it, the more it looks like variance among genetics in separate seeds. I did not see this much variety in individual plants with clones. So I think genetics (even among the same strain) is playing a role.
At this stage I just let them go but I wish I knew why the yellow tips also. It may be related to a response to the light by new growth.............. low nitrogen is also involved here. I just cut them off of it.

These are super lemon haze. I am thinking no more than a couple weeks to harvest (I hope). They are in week 6 of flower now and trichomes are getting cloudy. This photo is 5 days old. Each plant among 5 individuals looks different............. yet they all are similar (ha)

Your plants are lookin' nice! There's definitely the possibility you have a few different phenos of the same strain, that could explain the difference in their behaviour. I'm gonna pull back just a touch on the Bloom nute when I feed my ladies on Saturday and see if that takes care of the yellowing tips/edges, if nute burn is my issue. It would make a certain amount of sense, as I've only been feeding the higher amount for the last week or so, which tracks with when I noticed yellowing. The purpling in the leaves I have attributed to the normal coloration of the strain of the two right-side plants, I feel like this is about the right timing for color to start to develop. I attached some pics of my plants today--Day 34 of flower
