Diagnosis please: Snow White bottom leafs

Hi,

I've already looked for an answer but it's my 1st grow and I'm just a newbie, I couldn't figure out what the problem is...

I'm growing 4 Snow White feminized plants, the other 3 are great and growing fast, but this one seems to have slowed her growth and the bottom leafs first started to turn yellow, then some brown spots, and then just started to fall off :(

I've been watering and giving it nutrients just like the other 3, I don't think that is the problem. They're under a 250W HPS and have plenty of fresh air, never checked pH or EC. Humidity has been between 40-45% in general and temperature about 25-26ºC.

The first picture was taken 22 November, the second 27.
