Thats them after being under the 4 600w leds for about 36 hours. Some got it worse than others!
I wish Id known to give them a little more iron before getting them under these lights, So anyways I applied some foilar spray n grow that has Iron and Zinc about 48 hours ago, and already they look a bit better. Im going to just do a foliar spray about every week now until they get 100%

Right now they are veggin under a 300w MH just trying to get better, once they do they go back under the LEDs and crank up the co2!
 
That looks like Mg def to me, or maybe simply bleaching from the LED. Anychance of a close up? Im by no means an expert so would love to see a verified Iron def for future reference.

Been experimenting with these for the passed few months and almost certain Ive narrowed it down to being an iron def although I could be wrong.
The LEDs were hung about 4-5 ft away from the tops of the plants.

Looks exactly like this:

Iron and zinc are pretty rare deficiencies good catch if it is. Make sure you give them a good all around macro and micro nutes if you have it. I'm thinking CalMg, but additives like kelp/seaweed extract and sea90 have a lot of micro/trace elements and will address many unknown or mystery deficiencies. Your girls look really healthy other than that new growth and can probably take what ever you give right now(within reason).
Also make sure your PH is way somewhere(soil,water,nuts) just incase. I usually don't worry too much about ph in soil but it's worth a check when you start to get weird problems.

Can you get a closer pic of just one of you affected girls

I am a complete novice, but want to upgrade to LED around late June so starting all my research now. which is why I have been posting in this thread so much lol.

So eshine has these new lights with 20w LED, feel like that is a huge jump from 3watts. What would be the benefit, more penetration and a space saver?

eshine has poor reviews from what I've seen.

Knowing what you want, and what to expect in real life, make the biggest differences. There's nothing wrong with 3W diodes, or even 1W. Apache Tech uses 1W diodes, and have great results. A ton of people use Blackstar, and those are 3W. Figure out what space you want to grow in, and find LED's that meet your needs. If all you want to use is 2ft X 2ft, there's not really a need to ante up for the high dollar stuff. You can grow under an LED shop light. If you're tech savvy DIY is usually less expensive. Even if you have 5x5 or 4x8, there are still good options that won't break the bank.

Yeah your right either iron and/or sulfur def.............like tags said make sure your ph is in check before amending.......good luck grower

Using Spray n Grow along with Botanicare pure blend pro veg formula as a foilar spray. But also will consider some Liquid Norwegian seaweed, hoping to see some improvment, this will be day 3 after I sprayed. I will take some more detailed more pictures of the more sick ones tonight.

I was thinking of spraying a healthy plant and putting under one 600w led light and see how the growth is, just to know for sure if thats whats goin on...
Been feeding with water of a ph around 6.2 - 6.5, and right now they are in 2 gal containers with DTE Pro Organic mix, then gonna transplant into 7 gal n SS.
Only 26 days from seed

Thanks for the help, post more pics later.

Also do you think that having the co2 levels in the room @ 1500 ppm also contributed to the iron deficiency?
Maybe I should have started out low and worked up..
 
What panels do you have again? If they are decent panels with the correct spectrum there really shouldn't be any problems or that much difference from the lights. Specially if they were 4+feet over the canopy.

Love the huge TGA selection you got going

Thank you, and stoked to be growing some TGA gear for the first time. Looking to find some keepers here!
Anyways here is the ebay link to the lights I have

There is 4 or them over a 8 x 12ft area, and yeh I had them about 4 feet away from the tops. Also my temps with room never get above 80.
Just using this as a pure veg room for roughly no more than 20 plants and goin for 2 months then they go into a 3 x 1k HPS 8 x 15ft room.

So here are the updated pictures, these were sprayed 3 days ago and will spray again next Thursday.

Thanks for the reply, yep only 2.6ftx2.6ft. defintley wont need anything big want about around 100 to 150 wats. I am making sure to do ton of research before I invest.

You could go up to 275watts in that amount of space. If you want to do it on the cheap, two "UFO" style fixtures would be adequate. Not a whole lot more and you could have something like a California Light Works Solar Flare 200 (160Watts, 5W diodes, just under $400). I'm using the new Area 51 LED, 120w/155w switchable, it would put down a lot of usable light in that space, but it's more expensive. Kessil makes a pretty nifty "UFO" light, either H150(31watts) or the H350(71watts) can come in a couple colors and can be used as primary lighting or supplemental as well.

Those are just some of the options. When I needed a similar light, I had quite a bit of thinking to do before I pulled the trigger on a >$500 light.
 
Sadface- there's a new UFO type panel that is out/coming out, that would be perfect for your 2.6x2.6 area. I don't know where I saw it though. Instead of being a flat panel, it is angled outward all the way around. It should let you get the light a lot lower.
 
You can get ahold of BSLED and get 2x 140w UFO with cree chips and a great light for 550 ish delivered or 280ish a piece.. That's what I would do in your 2.6x2.6 2 of those would be great
 
I would not invest any penny in that BSLED UFO or any BSLED LIGHTs unless one can show me those LED chips are real CREE chipooooooos, as there are some many counterfeit Cree chips in there.
 
Yes, Great, Good, but which LED light should we buy , Damn it man get to the point!??!?! All that babble and not one suggestion. jeezus

Ants in your pants?

Too busy to read any comments?

Or do you just want someone to tell you what to do because you have no mind of your own?

I'll play along...There is no generic design or templet for LED's like there is for HID's such as hood size/coverage. HID's are pretty much all the same...yes they look a little different, but the hoods are all designed for 4x4 spaces and one bulb(yes a few have dual bulbs). This makes HID's very easy to compare with each other. But led's are all different shapes, sizes, and qualities. Companies are just getting to the point of good 4x4 replacement units.
So for led's it depends on your space, grow style, and budget.

Here is how I look at LED's in order of importance.
1) What is the par output in umol's (most companies don't give one on their website and that just pisses me off)...minimum 700umols@12" is the lowest end of my attention radar. 1000hps's puts out 1800umol@24" so that is my real goal.
2) Wattage to achieve output. (first total unit draw, then diode wattage and brand)
3) Coverage size and umol dispersion over the area (only strong in center or is it spread out)
4) Spectrum/wavelengths
5) Price
6) BS advertising/company image/knock offs on the market. (maybe they are the knock offs?)

Just the ways I personally judge all of them.

Apache Tech
Area 51
California light works
Lumigro
Illumitex

Those are good reliable units that will work how they say...or close to/could happen. There are a few more that come to mind but I don't trust or don't know enough about to support.
