I started flowering this Malawi on April 18. The catalog said between 11-13 weeks, I know that's just an estimate. Its been 11 weeks and looks no where ready to finish. I know it could take longer, but its just not filling in. Its grown indoors with the botanicare kind nutes, 600 HPS. Ive been growing for 15 years. Am I doing something wrong? I'm fairly new to sativas. The temps in my room are in the 80's and I have plenty of ventilation. pictured are the tops. Is this a really long flowering sativa thats going to eventually have buds? I grew some sativas last summer and they looked like this, but I ended up letting them flower to long, they never fatten up, but had temp. issues last year. If anyone has any suggestions, please let me know. I really want the sativa experience. Thanks in advance..
