I'm using two 75watt UFO LED. After a week a few symptoms appeared. Some leaves burns, can led cause that? Another one is some leaves bending downward? Is the distance too close or too far? Ants keep coming, i use some lemongrass spray, probably caused the burned,2013-10-02 08.47.04.jpg2013-10-02 08.49.25.jpg2013-10-01 09.00.57.jpg

I am still pretty new to growing, but I would wash your hole grow space down with a weak bleach solution to get rid of any bacteria and the little ant tracks, what kind of soil is that?

^^^ your mix/medium looks questionable....what's in it?? are you feeding them anything(hopefully not)?? and careful about your watering habits(only water when the growbags seem very light). Fastest way to kill plants under leds is constant wet roots.


ufo distance is fine and good luck grower

It's not the lights. I run possibly the same mini UFOs you purchased. My light distance is 8 inches to a foot away. No Prob.
You right about that spray.

Good Luck Grower

I'm using Advance Nutrients Sensi Grow Part A n B, it have the elements. Since all of u say that watering only when the growbag seems very light, but the nutrients need to be dilute in water, meaning i get to apply that only when watering?

AN A+B does not have all trace elements.
Whats your soils pH?

It's quite basic, around 8.3 ++

I think your water is not just basic but has a high Alkalinity, which is preventing nutes from being carried into the plant. The roots are pumping hydrogen Ions into the soil but there are no more gaps in the water molecules for them to flow into so they cant really do much.
I am pretty sure the most important thing is to get the Alkalinity of the water down not just the ph.

Ph, ph and ph bro. that is what you are seeing here if you ask me. As previously stated some lime would be in your best interest, not to much but do not be a pansy about it either. That is your water ph right, runoff or before watering? If that is your soil ph I would not even try to grow in that stuff man, not to be too negative... But it is def not the lights since it appears to be only your lower growth being effected

Please help. I don't know what happended to the plant. The lower leaves all yellowing. Is it the light does not reach there? Or nutrients deficiency?

Kinda need more info to go in if you want help bro. it aint the lights not hitting it, have you ph'd your runoff lately? What us your feeding schedule looking like atm? To me it looks like a severe deficiency, kinda hard for me to tell from the pics looking on my phone but either nute lockout from poor ph or just not enough feed depending on your medium. get us some more info to go on and we will proceed from there.
