WTF is wrong with this grow?

I'm far from a pro but I thought I was pretty much dialed in on the 818 Headband. Same grow, same room, same nutes, same everything. Half are frosty and half are not so frosty... I need some suggestions before I do something stupid like start sticking thumb tacks in main stems and kicking pots! Please see attached...

Heat or pheno expressiin?

I'm running a little hot like around 85 F ish.. but im using Silica and keeping my Co2 above 1200ppms

its hard to tell because you have taken pics with the hps on
but from what i can tell, its heat stress and there they look like they have a long time left in flower

if this is 85 f at the canopy level under the hood, its not down to heat stress
it could be low humidty and strong nutes

Damn. To complicated for me. I grow in soil. No co2. Water, fertilizer, smoke.

Both or just the one that has hardly no resin... The frosty side of the rooms heads are turning cloudy... I'm on day 4 of a two week flush that side. The not so frosty side I'm still giving them my late bloom nute regimen. So I'm thinking when the frosty side is ready for harvest, the not so frosty side will be looking better and will be ready to be flushed. I'm just not use to things looking so different in one room. 4 gavita Pros(hps) turned down to 660 in a 10 x 9... all my cooling comes from the frosty side so im going to assume you are right about the heat though I have 2 thermostats. Can I get some more tricome production or is it too late?

I know the only time I had that problem it was due to heat. Lower buds were frostier.

humidity is around 61 and I thought that was a bit high for flower... I was shooting for low 50s...

some of the lower buds on those are frostier.. It's been in the 90s lately over here... I'm going to turn down the lights to 600 I think one is on 750. And try to get back to 79 F. Thanks!

No soil for me... I started straight Hydro now "I'm in love with the CoCo"
