Thanks for being patient and waiting till your pics were approved.
It's still a bit hard to tell with the spectrum of the LED's, so I am hoping we can get more opinions.
By the way, I will be interested to see how the LED grow turns out. Good luck.

The hook leaves are the give away to me re the over watering. I have enlarged one of the images to see better.

i'm not using just the leds i took out the florescents i had in there because they were burning the plants and heating up the room allot so there just a 250 watt metal halide in there plus the led's

[Zenmaster]

so just dont water them for a few days untill they stand back up and soil is dry ?

[Medical Marijuana]

Yes, if you go to wet/dry cycle things should improve. Check this out http://www.420magazine.com/forums/gr...pictorial.html

ok kool thanks for the info dude i'll wait a couple few days see if they dry out and leaves get better or not

[Boss]

It may take some time. In the mean time, I would get those LED's 2" off the plant. They can even touch, they won't burn. You are getting a lot of energy put into stretch from the 250 being up high and the LEDs being 1 foot or more away. Just my opinion.

I came across this, which surprised me, as I initially thought the same as Boss re distance from the plants.

How far from my plants should LEDGrowLights be placed?
Position red and blue lights 12-24 inches from the plants. Positioning red and blue lights too close to plants may result in unacceptable growth.

Full-spectrum lights may be placed as close as 3 inches to your plants.

Growing Tips:

Reducing the distance between a light and the plants by one half increases the intensity of the light reaching the plant by four times.

Use more blue light to produce sturdier seedlings and to help contain trailing, sprawling or aggressive plants.

For leaf crops, switch to all red light at the end of the growing cycle to increase yields.

Blue lights may be used alone as a supplement for HPS lighting.

Red lights may be used as a supplement for sunlight or MH lights

Really? Wow. unacceptable growth? Alien plants? That probably just saved my kids sunflower, I would have had it 3" off the top of it :-) Looks like he is using all red leds.

Thanks for the info!

[Zenmaster]

yea i thought the red spectrum was replacement for the hps bulb not the metal halide and i did have the light placed right up against the plants but it gave them spots because the leds make a circle type shadow on them so i found it better to keep them about 6 inches or so away so the light blended equally around the whole room and the plants and didn't have that ring look from the lights on the plants like when u get them really close up oh yeah i churned up the soil with my fingers around the roots were they were not at so theres dry/stil wet dirt but atleast its halfway dry near the bottom now on one of the plants and not just dry at the top part and soaked near the bottom we'll see if that helps or hinders it just thought it might help so we'll see

[Zenmaster]

all of the top leaves are standing straight up almost on them now and when there almost up they start to wilt down and turn yellow now you guys know what would make them do that ?

[Boss]

I would suspect a pH issue, but we need temps, a description of the grow area, ventilation, lighting, etc.. that would help a lot :-)

[Zenmaster]

ph said it was just under 7 the temp in here is usually about 85 to 95 same in the room it got lowered allot tho since i took out the florescents its about 70 now and maybe 60 at night i have a 4' x 3' x 6' room and a oscelating fan at the top blowing on the Metal Halide light dont have a way to get fresh air in except open the door but i do that once or twice a day to keep the temps down and lights is just a 250 MH now and 900 red led's i thought the red ones were for flowering but *****s post tells otherwise i think i took some pics of them just now i'll post them when there approved but they just keep reaching for the sky now and when they reach the top or all the way stretched they start wilting and goin down and now its at the tops of the plant

[Zenmaster]

heres what the tip looks like now the bud is down at the bottom of the water leaf and the leaf is stood straight up and is about to turn brown n curl



heres why i think the led's shouldn't be used close up because when they are close up it makes a concentrated beam of light onto the leaf rather then blending with the rest evenly over the whole thing and the high power ones are even worse close up like the ever popular high powered ufo lights but i took a piece of paper because u can see the spots better then trying with a leaf because mine are all dead at the moment at the bottom of the paper you'll see the dots and as the paper gets futher away they blend together and become even rather then a buncha little dots right close up
