Paul Hornby here... Getting ready for my photo update but I wanted to share my first little bump in the road with you guys. About 5 days ago I noticed some yellowing in my new growth. This happened concurrently with dropping the light to 22" and stepping up the nutes. At this point I wasn't sure of the problem so I went to my friends at the local hydro shop and they helped tremendously.
The problem was peculiar because it didn't seem to effect the biggest of the lot, however the smaller more undeveloped ones were not looking good. Upon speculation we figured it could be a combination of a few things. With some research I found that different nutrients are uptaken by the plant at different PH levels. It was suggested to me to vary the PH within a specific range when flooding the buckets instead of keeping it constant. The frustrating part was that both me and my roomate were trying so hard to keep levels stable
...You grow you learn.
In addition, my friend(which is a hot little piece that knows a ton about growing. Can it get any hotter?) at the hydro shop explained that I might need to flush the salts out of my root zone. We raised the light up 6 inches as well in order to ensure little stress when recovering. All in all today they have made a full recovery! The new growth on all of the plants is now a lush green

We have most of the girls bent over now but we are still working on the last three. Also, we have topped some of them and the first one we did(Miss Blue) Has her two new growth fully developed. It is interesting looking at the first set of pics. They have gotten so much larger. Will update with pics on Friday!
