I hope it starts to fill out. I don't mind if it takes longer because this is the last one for the year as long as it finishes before the heat waves start.
Stick like buds that don't fatten up just produce lots of leaves

dont harvest so early
just did a quick search check this out .

The bulb we’ve linked to in this review has a 3100K color spectrum, which is our preferred bulb to use for all stages of growth. It is a flowering monster and does well in vegging too. There is a 4200K version available as well, the Philips Elite MW 4200K Master Color CDM Lamp, for anyone who plans on only using it for vegging or for those who prefer a full-cycle bulb with more blue spectrum light (to me, flowering performance is the most important).

After 9 weeks and all the hairs are turning brown and they aren't growing or filling in and the tricoms are milky it's time to chop otherwise if I leave it, it will just start to loose any THC.
I personally still question that because some folks dont make the 3100 any longer. Im not doubting you, im just weary
I can show you pictures of the past few weeks. The difference is huge
Well I have changed to a HPS because all I can do is eliminate all possible causes that I'm aware of.
Please do. I have grown before many years ago and I can tell when the flowers are not forming correctly if there is something wrong then waiting to see if they fill out I might end up with low quality bud. Keen to see the pics.

I never harvest based on trichomes and neither do any of my buddies. I don't even own a scope or loupe. That seems to be a technique primarily used by newer growers. It almost always leads to early harvesting which is also one of the most common mistakes newer growers make next to overwatering.
It is easy to tell when a plant is ripe just by looking at it, and judging by your pics they weren't even close to ripe. The last 2-3 weeks is when plants swell the most.
Hairs can turn brown from a variety of environmental factors. It could be heat, light intensity, RH, etc.
Whether you simply harvested early or have some type of other environmental issues that stunted them, I can guarantee it is not due to your lighting. CMH works great and can produce great flowers.
Capulator swears by CMH full cycle and he uses all types of different lighting.
Yeah I know people get good results from CMH bulbs. I just can't believe it's genetics because so many strains from different breeders have the same problem. I will just have to eliminate until I have found what's causing the problem.

A few things on this:
1 - how much time in the tent? Human eyes take a while to adapt to darkness - are all diodes / indicator lights FULLY off?
edit - deleted a bunch of completely unrelated content. I'd blame the weed, but I think I wasn't reading through... lol
- Passive intakes - Check em while you're in there, you got nothin to do for 5 min anyway.
I swiped a pair of my Wife's black leggings (not nylons - I'm a married man, I know the diff.) and used plain rubber bands to cap the exterior of my intakes - plenty of flow and it knocks the light down a few stops. Intakes are pointed at the floor as a last precaution.
(wish y'all could have seen her face when she caught me cutting them up. It's gotta be tough being her sometimes)
2 - Turn everything on and stand OUTSIDE the tent - all lights off in the room. I was surprised when I did this one too.
- Zippers - mine SUCK at the door. Bad enough that I clamped a thick beach blanket in front of it as a block. Then, during my walk around I had to apply gaffer's tape to 4 pinholes.

@hotrodharley I remember mounting the magnetic ballasts on plywood with no cover... the stupid shit that was done back then
I think we just aged ourselves here

It looks like you are overfeeding Nitrogen. In some of the pics you can see some leaves clawing with the leaf tips curling downward. Excess nitrogen can cause increased foliage growth and stunted flower growth. I would lower EC & back off the Nitrogen. Your Cal-Mag and Bud XL also contain nitrogen.
You should stick to the base nutrients, it is easy to throw off NPK ratios when using supplements and ultimately if your base nutrients need supplements then you should consider switching to base nutrients that are complete.

I don't bother looking at the trichomes either. And I agree that many that do are harvesting too early. They get caught up seeing a few amber trichomes and think it's time when it's not.
I did think it was nitrogen so I stopped the cal mag that has 2.0.0 but didn't help, I stopped using it week 3 of flowering. I have been feeding very low. Most of the leaves are fine the ones with clawing was they were against the tent. I will check it out again when the lights are on because I was feeding them 1.6 EC that includes my water that's 0.2 EC so really only 1.4 but yesterday they went from being 0.1 over on EC run off to 0.4 so will reduce my intake EC to 1000 and see what the run off EC is then.
The garage is completely dark as well I don't turn the lights on if I have to go in to the garage I use a green led light.A few things on this:

1.6 is still quite high IMO and if your runoff is getting up to 2.0 I think you should dial it back. I run DTW coco fed daily and I don't see a need to go beyond 1-1.2 EC. I was running 1.2 EC and had to back off to 0.8-1.0 EC cause it was a bit too hot for a few of the plants as you can see in the bottom left. Less is more. It's easy to correct slight deficiencies. Over-fertilizing causes more damage and is harder to correct because of the ph/nutrient lockouts that can occur.

I totally agree I found better growth with lower EC than high. I'm going to bring them back to 1.0 and once the runoff is the same will try and see what they are like with 1.2.if it's needed.
I have checked my timers so many times I'm a bit OCD when it comes to the timer as I know something like that can really stuff things up. I have also checked my tent for leaks and found none. I was hoping for an answer but I don't think it's going to happen.
