There is hardly any stretch because its very blue light. Blue light reduces stretch.
Is 5000k not as good as people say?

Get a lightmeter and I bet you'll find less than 15K lux at that distance.

for the sake of science i cobbled together some parts and i have a 6500K clu058-3618 on an HLG-240H-C2100B on an iceled active
(what?!? cobby went CV?!? - yup. only way to hit the 100-120V those suckers need
) - range with the dimmer is about 25-250W which the iceled can handle, so it s versatile addition to the arsenal.
im gonna use it mostly as supplemental blue hung high up above my 3000k 90 rig for vegging, but ill give it a go as sole light in a 3x3 and report back.
i have a feeling it will be way too blue by itself but we'll see what kind of midgets it kicks out

Oh the lil OBB there? She's monster cropped. They look like monsters. Weird growth characteristics.
Those are my SunCloaks. They're called Horizons. 100w T-5 replacements.
Oops Just realized the cloners behind that last pic.

So I added two 2700 LED bulbs, they are 1600 lumens a piece and supposedly replace a 100w incandescent bulb. I leave those on 24 hours and my regular cob light is on 18 hours a day. Lowered the COB down to 19 inches. Does this seem like a better height for veg? Anyone want to run the numbers for me on my lights PPFD? PDF is in my first post
We will see how it turns out, if they don't get any better within a week, I'm just gonna chop them and start over with the 250w 3500k Citizen I got, I'll just lower the internal resistor down a bit
Got the beans from strayfox gardenz

Why are you running rhe new bulbs 24 hours but shutting down the others? Just seems like more stress for the plants. Run them all 18 hours and give those lil bitchs a rest.any updated plant pics?

Agreed. Let them roots grow & don't water/feed until the pots/cups are almost dry.
If your working w/ seedlings, all you need are those led bulbs. You won't want 100+ w of your cob light until they get fully rooted & maybe into 6" Potts or whatever.
100w of my Horizon does 12 clones until they're ready for 3 gall pots. Then I go up to 200w for 8 pre-teens (3week-1month) & up from there. Here's the ones I posted earlier just transplanted w/ 4 clones added last night.
Here's 2 in 6" Potts using only one 15w, 5k led spot light bulb. 
These were vegged under 33.3 w of 6k a piece until a week ago.

Definitely did not know a little 10-15w led could provide those results. How long have those been in veg and are those from seed(under the 15w)? Nice, I put the little ones outdoors and am starting up a bunch of peppers,tomatos so maybe I'll start them under the 2700k 10w bulb, I didn't think that 1600 lumens would be good enough. Thanks for all the advice so far

Those 2 are clones planted on 4/22 & were vegged under the Horizon @8 w each until now. Now they're under the 15w spot light getting 7.5 w each. I use the Sylvanias but you can get a generic version too. Got them @ Lowes.
If you get or got the led bulbs, I recommend getting the ones like I use w/ the lens/optics.
I've vegged them pretty big using 1 each plant in 6" Potts. Right up until they were ready for transplant.

as a supplemental its doing great. right now in my 3x3 i have the one 6500k at 140W and the 9 3000k 90s at 110W (total for all 9). just flipped will get some pics in next few days. gonna preflower in the 3x3 for 7-10 days then open them up into a 4x5 with 3500k 90s

You own CLW too right? How are they for vegging? My Hydroponics Hut works really well in veg. Actually comparing it to my 600w MH Daylight Blue. Even know there's a ton of red in the HH, the MH seams to be inducing more of a stretch.
Personally, I think 5k is a perfect veg spectrum in white.

So my 5k is on a 9" plant and it seems to be doing well. The plant is so finicky though, shows cal-mag problems, I feed it a bit then it burns the whole fucking plant. I'm getting so impatient with this damn thing.
I started my seeds and they all sprouted the 21st, they are only under a 15w (1600 lumen) A19 bulb and all of them are all ready turning yellow on the leaves. It's a 2700k bulb. I don't know what the hell is going on, are they just bogus seeds, am I just running into bad luck. I have no fucking clue, my asparagus and leafy greens are doing a OK in the promix outside.
I'm gonna see if my promix in my container has gone down in acidity and that's perhaps why all the growth looks like such shit. Im gonna gently get the seedlings out of the mix anyhow and put them in jiffy mix.
Shit blows, when you spend 600$ on LED and 200$ on seeds and they are under-performing the normal bagseeds and Mars/HID setup I have been running for years. I dont know what to make of it. I'll be reporting back with a pH test when I get back from the box stores. Next round I may just go back to organic, honestly the yields have not been that great in coco or promix, especially not worth the cal/mag bullshit when I can just add a bit of Gardeners lime in soil and be done with it.

Ya I was gonna say check your runoff ph. I think 16-18" is good for cob height, im running about 12-14" and it's not awful but I have height limitations, would like to go up to 16-18". Anyway, post more pics of your plants. I also have had calmag problems and a little yellowing but not to the extent I saw in your first pic. I just get yellowish new growth and stripes of yellow on older fan leaves. I am going to try epsom salt in my grow to see if that helps, possibly we are needing more magnesium or sulfur which epsom salt provides. I don't see how your 5000k isn't doing well though other than problems with soil or having the lights too high.
Maybe give your plants a good flush too, who knows what kind of lockouts you might be having.
