Ok, my one allowable semi rude comment.....
You can make it grow by stroking it.
End.... As you were.
I have used AN and I would start at 1/2 recommended. Watch your leaves and be ready to back off or up across those three (Micro, Grow, Bloom). I would use full strength HydroGuard and depending on your water a full recommended dose of CalMag.
Its expensive so I switched to GH, but left them for reasons not associated with quality of product. Ended up using Future Harvest on my last grow.
Next year will start with AN and probably finish the year on the same.
