End of 6 weeks kind of yellowing

I'm 5 days into week 6 flowering and these are an 8 week strain. Is it too early for this much yellow? Been around high 70s for temp not sure if that's why?

I don't think it's because of temps , I've seen your grows over the past years, maybe they're a little hungry for N I think it's also a little early. Making lookin grow btw brother.

It just might be. Normally, it's the lower leafs that start yellowing out first. All of yours appear to be right at the top of the canopy. As far into the flower stage as you are, I just don't see it being nitrogen deficiency.

If you're taking your temp in the shade and it's high 70's, those upper leafs under direct light are probably hitting in the '90's...so I think you're right on the heat being a factor.

There either locking out nitrogen or your not feeding them enough n.

I have 2 digital thermometers. One on the wall on the side of the room and 1 that I hang at canopy level under the lights. The room stays between 74° and 78° and the canopy stays between 75° and 86° at worse. I did veg these plants for an extra few weeks and the roots were ridiculous. So I didn't know if I possibly under fed them Also? Buy with it being a little warmer I had to feed them every 2nd or 3rd day so I cut the nutes back a little. So I'm not sure what happend. I just hope they fill out a little better over the next 2 weeks or so. I've got a mini split I just haven't hooked the damn thing up yet!

Then it's not the heat. It's probably going to be what westcoast420 said. 86 at worst just isn't enough to do that to your plants.
