i dont feed it much..i been using miracel grow shakin' feed slow release. which feeds up to 3 months(i used that about 2-3 times during veg) and just used this tomato food i bought at k-mart for like 3$ its water soluble and i used 1 teaspoon for every gallon as directed.

another question..dont sativas double in height during early flowering. i cant complain because the plants already huge but growth has stopped. i was excpecting a 20 footer.
