3 RQS Autos (First grow)

Growth has been pretty good this week. Starting to see trichomes appearing on the NL and Skunk. Not seeing them yet on the Kush though. I know I had said that I wouldn't be doing any more defoliation, but needs must. Airflow requirements and the worry of mold developing drove me to it. The purpling has got to such an extent that the upper main stem of the NL is fully purple. I'm assuming at this point that this is an issue with the root zone and not just that I'm not feeding the plants enough phosphorous. In order to try and address this, the plants have all been flushed with water and will resume normal feeding in the next couple of days. Other than that, the tent is definitely starting to smell stronger when I unzip it.
