ok so, in my flowering closet i have two mother undefined indica/sativa (70%-30%) plants. one of wich is doing incredibly good. flourishing beautifully, real thick pistols and resin covers leaves. while the plant next to it has stopped growth, and has and upward incurl on fan leaves and some higher branch leaves.

i have flushed the soil that it is in, and repotted it, i have just started to give it foxfarm tiger bloom, and i am hoping that will help.

i am fairly new to cannabis horiculture, but i know what i am doing and i can understand advice so any help you can give me would be great.

what could my problem be?

and what should i do?
