Sativa-dominant auto's

More explosive growth from last week for Bruce Banner (grew from 13.5 inches to 15.5 inches in height). Don't want to risk LST during the flowering stage, ven though it seems to be re-vegging after changing the light source to the grow light. For Amnesia Haze it just seems the white pistols have gotten longer. Added CalMag at the recommended dosage (once per week) in case nute deficiency (not just light burn) might be contributing to the yellowing leaves, more for the other strains that I'm growing than these, but so far adding CalMag doesn't seem to be affecting them negatively.
