Speed Bud Auto (LST vs Non) Winter Grow

Both of these are looking close, with the LST one closer. At the beginning of the week it appeared that the LST had a deficiency or make it was Ph fluctuatations, either was i gave it a small flush with pH water then I gave it probably it's final dose of FF nutes. The next watering I gave it KNF flower inputs as well as a bit of compost extract and SST I had made for my other grow. By the end of the week it wasn't looking any better on terms of the deficiency but it did begin to show a good amount of amber trics. I'll wait for those to mature a little more before the chop, but I think it'll be by the weekend. The non-LST got the same nutes minus the flush. This one is also showing some amber but less, and it still had a significant amount of white pistils that I'd like to darken and curl before I chop but I'll go by the trichomes. I have maybe one more serving of tiger bloom that she'll get before changing both them over to just Phed water, maybe some KNF but idk.
