Son dont worry about lower, older leaves yellowing. Its when your shoots and top vegative growth u wanna worry when talking bout yellowing leaves. As long as its the bootom older leaves, just cut the fuckers off as it's normal for old leaves. it'll save alot of energy not having to try repair old leaves and slightly,indirectly help it to bloom.

You wanna be glad that its got that tall. More bud. I'm breeding all kinds of strange Auto's. You gotta be patient and a little forgiving as theyre relatively new strains.
Are you using a bloom booster like Top-Max or Canna-bio-boost? That'll help
