Not many crystals

I just cut down one of my plants. I have another plant double the size that dosen't have much for crystals. What gives?? Planted at same time. Also, found a tiny amount of mold on just one of the buds. I removed it and totally checked the plant over. That was all there was. Supposed to freeze tonight and rain tomorrow.. Kinda worried! Forecast looking good for the weekend though. Hoping for the best. Thanks for any info you may have for me.

well unless they are the same strain you cant expect them to finish at the same time. even if they are the same strain it could be a different pheno that takes longer to finish. it might just be a strain leaning on the sativa side and in that case if it is freezing and raining alot where you are already i doubt it will finish, sorry
