white flies?

well since i replanted them in I haven't added any nutrients.

try using 1/4 strength nutrients to feed them a little. Also the red stem usually indicated a deficiency i forget which it is.. magnesium or manganese one of those i think.

k thanks, i ended up buying some Fox Farm Grow big and that helped them. i guess they just needed some food
