***Are A Couple Yellow Sopts Bad?bubbleponics---W/pix***

I have 2 orange kush plants in a 7.5 gal bubble pon system. I just started my half grow and half flower solution this past Sunday. The yellowing is only on this leaf and a small amount on the the one next to it. Is this bad or is it just a change in the plant from solution?

***Top left corner shows leaf.
Other than that, how do they look?
++REP

nothing?
A little more has kinda shown but nothing major.
Anyone have a word?

Im a few years late on this reply, but nah.. you should be ok lol
