They need a light prune to get your branches into light before they flower, go super easy on nutrients like 1 quarter of recommend dose, you are allso overwatering, stick your index finger into the dirt to first knuckle at edge of pot if wet do not water, pics are 2 Skywalker autoflowers at day 33 from sprouts pruned off 2 sets of fans off larger plant to get branches into light, you dont want to prune in flower unless your slowly defolateing, in veg i feed botanacare pro grow 2ml per USgal then water down, if your useing a good mix feeding is optional, allso a light prune will not only get your branches into the light it improves airflow, once they top off or rather stop growing vertical and are in full flower i use
Atami Bloombastic 2ml per USgal but you must go light or you will burn them, autoflowers are not photoperiod plants and you do not run the same have been running autos for over 9 years the biggest mistake i see is overfeeding and burning overwatering is a mistake bc autoflowers have very weak root systems that is why there so easy to burn overwatering can mess up your root system, i would let plants dry out give a light prune water check ph then let them alone.
