Here we are on day 51, I think the plants are done stretching for the most part. These autos have really filled out this 5x5 nicely. I have gone through and trimmed off most of the undergrowth and lower bud sites. I have some new nutrients coming in from CropSalt (https://cropsalt.com/) that I think I am going to switch to for the rest of Bloom. I saw they have a finisher called Cake that is meant to give the plant a bit of what it needs during the last few weeks with no nitrogen, so you still get the benefits of a long flush while giving the bud sites some extra nutrients. Flora Trio has been working great, but I would rather just weigh out the powder and mix it up in two parts instead of having to go through the process of adding cal-mag, then micro, then bloom, then grow in a bunch of separate steps. I also feel better about proper dosing when I can weigh them instead of trying to measure liquids. Overall I am super happy with how this grow has turned out so far. All of the plants are relatively close to the same size and for only topping the canopy is relatively even.
Edit: Got the CropSalt in the mail and was due for a res change. Mixed up a batch of 3.4 grams per gallon of Part A and 1.74 grams per gallon of Part B
