Im use to growing a fast flowering indica sativa hybrid, so i bought liberty haze and grew 1 seed from my five pack . when it was big enough i took 8 clones, rooted them, veg them one week, topped them with 6 shoots. Vegged 7 more days and threw them in with my 30 hybrids. My hybrids blew right up fast like they always do. Like you said my libs going wicked slow. Then from day 30 on they exsploded blew right by my hybrids. Im at day 43 and the six main buds are huge. Smell like limes and show no signs of slowing down. They are on par with barneys description. "Long dense colas start to fatten up in the last 3 weeks of flowering". If your pheno is similar to mine hold tight, it should kick in to overdrive any time now.
