Hello,
After looking at your feed, you are feeding much, explains why the buds are so small in week 3. Try big bud, or any other bud boosters, such as high in P and K. Also, 84 degrees F is too high. Drop your temps down to 76-78
Downward leaf curl aka the claw is usually the first syptom of over watering or soil toxicity. It normally indicates theres a root problem with the roots.
