Hey sup guys, been lurking this site for awhile trying to gather up as much info as I can on growing. About 2 weeks ago I started my first grow and planted a couple bag seeds, out of about 5 seeds only 2 ended up sprouting and started veg growth. The plants are both at 3 nodes each so I haven't started any neuts yet at all, just plain tap water so far. The medium is a mixture of potting soil, worm castings, sand and perlite. Anyways, one of those 2 plants is developing some colour lightening on the top leaves after a week and a half under CFL's in my grow box. It kind of looks like zinc deficiency to me, but then again this is my first grow and I have absolutely no idea.

I might just be worrying too much and it could be nothing, but I'd rather be safe than sorry. If anyone could let me know that would be awesome, thanks.
