This could be good or bad...?

Ok so im 4 weeks into bloom. I really dont know what kinda strain this is. I got the seeds from my uncle. All of the plants have white furs except this one plant. It looks like another in the background is purple but i used uncle bens 4 main cola technique so thats just one of the other colas in the background. Is this possibly a purple strain? or do i have my lights too close or something? Basically i guess what im trying to ask is, is my plant OK or should it look like the rest of them? Pic 1 = White fur'd plant, Pic 2 = Purple/Pink furs.

your plants are just fine. the white hairs are called pistils and eventually turn color on all weed plants

you have purple hairs good shape be happy

Sweet. Im sittin here tokin up and thinking way too hard about it. The main reason i questioned it was because the pistils were purple but not the calyx's, they are lime green. Im happy tho as long as they are healthy, any color is a good color to me! Also on a side note, is it normal for them to smell almost like ASS if youve been trying to give them a hefty dosage of nutrients? I havent burnt even the slightest tip yet, but when i smell them they havent started smelling like pine and lemons yet, its more of a ummm.... nitrogen smell maybe. Not 100% sure.
