This week, I have been trying to manage stretching. I have been trying to keep temps low for the first couple of hours of daylight, but the stretching seems to happen during the dark period.
I am pretty much completely out of screen holes for training, so I have been tying down tall shoots for training as best as I can. The canopy is only about 8" thick, but I continue to remove fan leaves to improve air flow. Some spots get condensation when the lights go out. I changed the timer on one light to go off 5 minutes after the other to give my equipment the chance to lower humidity before the temp drops. I added a couple more fans to hit some spots that weren't moving enough. It seems like removing fan leaves is one step forward, two steps back because each time I remove a lot of fan leaves, the plants come roaring back with more growth than before. I am ready for the stretch to end before my scrog becomes just a skeletal support system. I have spare nets in case they do need support.
My initial 20 gallon mix clocked in around 600 ppm, but it spiked over 900 the next day. I have been adding 5 gallons of plain water every day, and the ppm stays around 550. I guess that is the concentration they want. Funny, I thought this strain was going to devour nutrients. I have no deficiencies whatsoever.
I did have one issue after the rez change. I noticed the solution was not getting to all of the buckets. The GH Waterfarm kit I am using has 1/2" tubes which are blue and translucent. There was algae completely blocking 3 of the tubes. Fortunately, I had the foresight to install shutoff valves on the buckets, so removing and cleaning them was easy. There were some roots beginning to grow into the tubes which will become a problem in the coming weeks when they begin to clog the tubes. I don't know what I'll do since I can't lift the buckets, but I will figure something out. My opinion of this expensive bucket system is not pleasant.
