First time trying a 3000w LED

How long have they been flowering?

Is it possible to turn down the power or dim your light so it's not so bright?

In my opinion;
It looks like your plants are getting blasted by the lights. If you've only been in flower like 7 weeks, they might be able to fill out a little if you can make the environment a little less harsh for a couple weeks. You can see white hairs and a little puffy-ness, like they're not done.

But if they've been flowering for 8-9 weeks already they're probably just fox tailed, with a fluffy structure from the harsh lighting. If that's the case they probably won't get too much better.

I guess if there is no dimming, you could also hang them a bit higher and loose some light on the walls of the tent.
Concerning what to do with the plants... no idea.

if you can let them go at least another week you will be glad you did

Thanks for the reply, sorry for long wait, had a headache earlier so took a little nap.

I believe they have been flowering from around 01/07/20.

The only dimming option would be to put the light back into veg mode, which I don't think is going to help much.

As you say Keesje could try to take higher up, but unfortunately I'm already at my limit Hight wise for the tent. Hence getting a slightly larger tent, or I hope to soon.

Thanks Powertech, I will try to let them go another week, would like to see some more amber etc before cutting.

It has to be said that in terms of colouration, they were looking very green about 1 to 2 weeks back with the same current light height, I think I may have dialled back on the nutrients a little early.

Smell wise they are quite lovely. Its a auto flower and oddly I've got 3 varying heights. Even the tallest for being so close to the LED doesn't have any major burn up top, just the yellowing of a lot of leaves and a few brown that have fallen off.

Towards the end of flower it is best to reduce the amount of light hours as well as dimm lights slightly. Kind of like the sun does in nature during that time

Thanks I figure I could just swap out my new led for the old one as one way round this for now. Or yes swap to a 12 / 12 schedule.

Sorry man, I didn't realize that they were autoflowers, I was thinking about photoperiod plants.

I don't know if you even count the flowering period for autos, of if you just count total days.

Anyway, everybody says go a little longer, so go a little longer.

Darox · Aug 9, 2020

Thanks for the reply youraveragehorticulturist, yea think I'm going to give it a while longer in general, giving them some slight nutes to try and help, but will see where they are middle of August.

Out of interest does anyone know a good pot size to maximize on indoor grows whilst letting them grow to a decent hight?

Pretty sure your issue has little to nothing to do with your lights. It looks more like a nutrient issue. Maybe PH or pest? It's hard to tell. You are rocking a little too much light per sq foot, like somebody previously mentioned.

I'm guessing you're on a limited budget, due to your choice of light. There are much better lights in that price range though. Look at Mars TS series, Spider Farmer, Hortibloom, or Phlizon. Any of these would be better than the light you picked up.

If you have the coin, go HLG or Timber.

As I'm using coco I tend to keep my ph around 6.0 to 6.2.

If you mean pesticides I don't use them. Or if you mean actual garden pests, not had that issue at all since good coco is a bit like growing in hydro.

Thanks for the light suggestions, though must admit unlikely to replace the new one soon. Will see how it goes with the next grow and keep up the nutrients longer.

Hopefully a larger tent will offset it a bit as well.

Thanks.

Darox · Aug 12, 2020

Not sure where you get that math, considering today is 14/08/20.

Keesje · Aug 14, 2020

Don't you think it has to do with how the dates are set?
Is it month-day-year or day-month-year?
You 2 are in the movie "dumb & dumber 3"?

Darox · Aug 14, 2020

Ive just never seen why anyone uses month day year. Logical progression from a uk perspective. :razz:

Keesje · Aug 14, 2020

The UK, the country that still uses Stone, Pint, UK Gallon... that kind of progression?
