911- leaves turning yellow

My leaves are turning yellow and crispy. I went away for 2 days but watered them before and as soon as i got home. when i got home i noticed the leaves were a little yellow and very crispy. i watered them with both the nurtient mix and just plain water. the buds on them are pretty full of resin so i was wondering if the buds are taking away from the leaves? I didn't leave it for long unattended but it seems like she is going to die on me. any help would be appreciated as i dont want these girls to die!

what size container is that? i cant tell by that pic but could be rootbound. Also it ia natural for bottom leaves to begin to turn yellow towards end of lifecycle.

any chance of saving them?

yes what size container is that
I cant see it well but looks root bound u may wanna transplant. Post pick of roots and i can tell u 4 sure

yo man its the plants process at the begingging of flowering and through out it that it will use up the nitrogen provide and use the N in the process of devloping buds! just pull them off and dust it off your shoulder, its natural man! hope that helps!

the container is 7 liters with 3 small plants no bigger than 24 inches in them. I did transplant them into another container with more room and soil...lets hope that works. the roots were filling up the container but there was still a lot of soil left. so the roots probably had a little bit of room but not much. thanks for the help. i hope she turns out ok.
