Started a new thread as per suggestion,accidentually posted on a bumped older 2009 thread... Using Single mars 300W led and plant is at least 12" from the LEDS with no signifigant heat issues from the light or room. (Temps never lower than 65-70 to as high as about 78 to 80 on occasions) My leaves on the top of my one plant are slightly curled shaped and look to have a very lighter discoloration/shading to around the serrated area of the leaf. Its like a lighter green than the rest of the leaf. Grown in FF OF soil with PH'D 6.0 tap (distilled open air) runoff tests 6.0 - 6.5 Is this a concern? Im torn between it being normal or Okay,or just moving the light/plant further away from eachother. My other plant being a sativa is about 5 inches taller and close to nearly 9" from under the LED panel and shows no similar problems with the leaves like my indica does. Making it harder to determine if its genetic based,nutrients,or just a highersensitivity to the LED for the one indica plant. Any help greatly appreciated!! New to being here on these forums also as well as growing so please be easy on me lol. Attached photos both with and withour flash,growlight, andwith HDR to give the most accuratelook at how they appear IRL.
