K im not sure if this is a big deal at all but id rather be safe then sorry, my plants are exactly 3 weeks old, and i just recently found a couple brown spots near the edges of my newier leaves. Sorry about the pic but couldn't get it any better but its the yellow dot on the big leaf on the right, and next to the little yellow dot there is a little more discoloring. Please help becuase i dont know whats wrong or if this is anything to be worried about, i have them in my closet under 4 40watt flour and 2 65 watt grow bulbs (nothing special just cheap), water ever couple days sometimes once a day, about 80 F, 28C, any ideas, thanks
