I grew Blueberry and AH separately. The Blueberry was a trooper and unfazed by my mistakes. AH on the other hand was tough. It was my second or third grow. The moderators stepped up and got me through it. Most of my I problem was my pH was way too high (found this out once I started checking) and I nuked one with Nitrogen overdose.
Two threads dealing with my issues. Maybe they can help
