Led Lights And Unfinished Buds?

[cottageman]

I am on my second harvest now, and I have a lot of buds that are fluffy and not finishing. My environment is more than fine, same thing with my nute schedule. I am not a new grower but I am new to growing under LED and I have only had this problem with my LED lights. I have 2 vero 29's at 3500k and it just seems like they aren't adequate for flowering because both times even nugs very close to the top are fluffy and not finished. Any thoughts/ suggestions would be greatly appreciated!

Maybe lights are too close?

What’s your temperatures at the tops under the led. ?

Led won’t feel hot but they do put off a heat. Heat stressing up top could possible cause fluffier tops. Any foxtailing on em under led?

No I dont have any bleaching and the top buds for the most part are fine, it's really anything below the top layer, even on the main stem

No foxtailing, or bleaching. Temps never got passed 80 the whole flower cycle. I will post pictures of what I mean when they are done drying in a day or two. Top colas seemed fine when I pulled them but I will double check when they are done drying. The one thing I can think of is maybe not enough red light for flowering?

Sounds as if you might be chopping them too early. Do you check the trichs for maturity? My finished flowers under QB led boards or cree cob led are more compact then when I used cmh or hps.

Yeah, I got the strain from a very trusted dispensary and it is a solid 9 week strain. When I checked the trichs on the top buds the day before I chopped they were all milky and maybe 5-10% amber. This happened my last run as well but it was a different strain. no chance its not enough red light? I am just confused because I have seen great end results from other growers using the same nutes, and even the same lights nut my environment seems pretty stable as well. Would light leak maybe cause this?

What are you pushing wattage wise out of those cob's. 100 watts won't do much for a flowering plant.

200w total, 100w per light and I also recently added a red LED bar for flowering so hopefully that will help as well

 

[Grimmstone]

My guess would be not enough light. 200 Watts is not a lot. What size space are u trying to cover?

just a 2x2, what it says it will cover but I am assuming that is the problem and I just need to lollipop more instead of just deleafing. These are some of the top nugs that are almost done drying and they turned out better than I thought

 

[OldManRiver]

Dunno what you're expecting; those look fine to me.

You could try some side lighting. Do you have reflective walls?

yeah it's in a tent with reflective walls but i am really waiting to upgrade my circut breaker so I can have more amps in there because I'm planning on putting at least 200 more watts in there so I can get the light coverage I really need

I'm running 250w 5-cree cxb3590 in a 2x4 space for veg and about double in my flowering cabinet also 2x4.

yeah im going to keep these vero29's up and I want to add 150-200w of plc photo boost board set up in a fluence like design so I should get much better coverage than before

That should do it.

 

[cottageman]

That should do it.

im excited to try that new layout. I am building a warehouse this year and this will be my first test run to see if that layout really does compare to a 100w d.e. hps

 

[New school]

You'll need more for a warehouse. Lol
