I agree pic's are lookin good, i wouldn't expect much more than that in size for week3. Check mine out if you get a chance, and let me know if you're lookin for bigger buds than i have at middle of week6. I think lumens=bigger buds. The more light, combined with higher intensity should produce bigger buds. I'm having a hard time getting their nutrient levels at the right threshold. Also didn't know ppm should be measured before all the other goodies are added. Are you're plants sativa dominant? they are stretchy, kinda, exactly what i hope my Chocolope does!
