Hey guys, can anyone please help me figure out what is going on with this seedling. it has been 10 days since she popped out of the seed and 7 days since she's been above ground. She is starting to show some brown spots and areas on the true leaves. I have not fed them any nutes yet just distilled water about 6.3PH, and they are growing in a coco coir perlite medium. I have a 23 watt daylight cfl about 3-4 inches away from them Could it be a calmag deficiency? is it still to young to start giving low doses of calmag and grow big.. I don't know what could be the issue, this seed is a female seed c99. I have another Casey Jones doing fine under the same circumstances. any help would be appreciated
