well i can definitely say its not dry because drying starts at the tips of the leaves, and your leaf tips are green yet.

I'd put my money on nute burn. have you recently changed the amount of nutes you give 'er?

dude im no expert..but i think thats normal..those r the first leaves to come out..the oldest ones..so just leave them and they'll fall out..and watch if any upper leaves start gettin yellow..if not than everything is aok!

My old leaves that don't get enough light turn more yellow and droopy then they dry out. You can drop a few bucks and pick up supplemental t5 lighting and try to allow the bottom leaves and bud sites they form to grow out a little. I wouldn't worry at all about the first 2 sets of leaves though, usually they are small as shit and can't branch out. I find the bud sites that come from them are also smalllll even with side lighting.
