damaged roots? can i fix it?

Hey everyone, well i have a plan that looks to be in very bad shape, at first i figured it was because i had horible driainage, so i transplanted the plant into a soil/perlite mix. while transplanting i noticed this plant had barly any roots compared to my other plant. (both are female). So my guess is my plant is in such horible shape because of the damaged roots, is there anyway i can fix this problem? or am i doomed. Or can it be something else?This is my first grow so i really want the best for my girls. Here are pics of her.

anyone wanna help out? i can find any info in the fourms

Let your soil dry out for one. cannabis doesnt like wet feet. let it search for the water. maybe add a bit of B-1 to your watering it will help the roots grow. looks overwatered, roots wont grow if its overwatered, they will die off, probably what happened. i let mine show me they need water before i give them some. if your giving nutes keep it very low stregth, they are still young. gradually increase as you go, i stop at 1/2 stregth with great results.

Poke holes in the bottom of that bag and place the bag in some tupperware. As water sits at the bottom of the bag, fresh oxygen is not available and bad bacteria is growing causing damage to your roots by increasing the acid and "souring" the water. Always have drain holes in the bottom of your planters to avoid these problems.
