Gorilla Glue/Sour Diesel Auto Grow-Ist

11/22-Start of week 4. GG's are looking good overall. GG #1 keeps moving along nicely although I wish I had not broken that branch or it would be really great. After topping GG2 it is coming along great. So much so that I moved it into the grow tent and demoted GG3 to the other grow area. I've been aggressively LST and removed some leaves to get some light down low. I'll see how she does. Continuing to adjust LST on both SD's which are both looking good at 21 days. 11/24-Watered GG#1 and SD#1 1/2 gal each with a 25% dose of Sensi Grow A&B 8 ml/gal ( 4 and 4) and 6.5PH. Put the plants out in the sun for a few hours because it was so nice. PPFD was about 1200 in the sun. 11/25-Raised the lights 2" to account for growth in the plants. PPFD is around 600 ish with no adverse affects observed so far. Did a fair bit of defoliation on all the plants to get some more lights down low. I'm hoping that I'm not overdoing the LST. We shall see. 11/26- I noticed that the GG #1 had a brown tip developing on only (1) leaf. Not sure what that is since none of the other plants or leaves show anything similar. Will monitor. Received a new touchscreen controller from Optics LED that will allow me to fine tune the lighting by 1% increments on the Slim 320S. Happy to have it for the rest of veg and then into bloom. 11/27-I think I figured out the cause of the brown tip leaf on GG #1. I purchased a heater to place in the tent to keep temps steady. I think even though it only ran in short stints when temps dipped the intensity was pretty hot. And it was aimed a bit toward GG #1. I've moved it to the other side of the grow tent where there is a bit more room and I made sure to aim the airflow clear of the plants directly. Will monitor. Did another watering but this time increased the nutes to 50% (8ml per Sensi Grow A&B) of recommended levels . One half gallons per plant for GG1 &2 and SD 1&2. PPM of about 900 ish on this watering with 6.4 ph. Will monitor for any adverse reaction. 11/28-All the plants are looking good. No adverse effects observed from the increase in nutrients which is great. The first 2 plants I topped, GG#1 and SD#2 are really shaping up nicely and getting close to that even canopy I'm looking for. All the plants are starting to show the first signs of stretching. Still no pre-flowering yet. raised the lights a couple of inches to account for growth. Increased red lights on Slim 320S light to 32%. Blue channel is at 100%. PPFD around 700 now. 11/29-Overall the plants look good. I detected a couple of very tiny white tips on the leaves on GG#1 and SD#1. Almost unnoticeable but probably a sign that I should cut back on the Grow nutes to 25%. Both GG1 and SD1 are getting that even canopy look. SD2 (untopped) is trying to get taller but the LST is helping to keep things relatively even. The SD's are shaping up to provide an interesting look at the difference in yields from top/no top. Both GG2 (topped) and GG3 are just not getting taller or wider. They both look healthy but there is not much room between nodes. Don't know why. At this point I'm seeing the very earliest signs of pre-flower on the SD's but not on the GG's. Finally, I did a trim on SD 1&2 as well as GG 1&2 to open things up a bit.
