Pretty bad leaf curl. Help?

might be from a bug infestation that I got rid of a few weeks ago. What can I do to fix this?

did you overfeed them ?

well i haven't run into a deficiency looking like that yet. but i have had root aphids, and this looks eerily familiar to me. whatever it is they are consuming your roots. all new growth is dead!

haha bad news. your bug infestation is still alive. buy a pack of cigarettes and put em in a blender then put them into a gallon of water and let it soak over night then strain out the tobacco and water your plant. this will kill the bugs, you can use 2 swishers instead, i did this in order to save $3... for the mj fund
