that's weird bro, you can see how healthy they are, so that obviously is not the issue, and you scene/set-up either.....man, very frosty though.....are they all uber frosty?......one of my chernobyls was like that last month, she never really filled in, but it was some of the strongest herb i have ever grown......
ya they all are UBER!!!! Frosty,,, #3 is 2 days behind 1 & 2 and and is about the best looking one for filling out its defenitly bigger then 1, 2, 4 & 5,, But still its way way smaller then a couple i have thats 10 days behind it, all 5 are about the frostyest plants i have had to date lol, and also some of the healthyest, so it has me stumped!
