Wondering if doing another defoliatation would direct more focus to the main sites?
Also I have three other plants that are about 2.5 weeks younger, so I have to keep an 18/6 light schedule. Would I have to switch the flowering plant to 12/12 even though it's an auto?
Just trim the lower branches, the autoflowering plants don't have their photoperiod changed; to get good yields, they need to be in 20 hours of light and 4 hours of darkness.
I wouldn't defoliate that plant. It looks a little underfed though, increase your nutes slightly for some better growth. Autoflowers can be run at 12/12 but I don't know to what risk your yield may have doing this. 🌱👍
if you have some axillary growth very low, maybe.. .but looks good. avoid the 4" stem and 1" fluff bud at bottom, but becareful further up. it's probably done growing eh? should be able to see what is worthwhile and what is not, now.
