your right they are ice crystals not THC this is a one leaf plant. MJ (weed) is a 3-15 tier leaf most common a 5-7 you can produce a one tiered leaf but thats under way to much light and the top leafs would be one and by the 3ed tier down it would be a 3 leaf !THC crystals do not form on the plant UNTELL it is BUDDING and there is not one bud there.
