Northern Lights, Tan. Dream, Blueberry!

Wednesday means Week 4! Just for fun, I added three screenshots; one is the Humidity/Temperature for the grow so far, the other is just the last week and the third is a single day. It does go up and down globally based on our outdoor temperatures (we don't have AC, but it it slightly buffered by being indoors, basement level and with dehumidifiers keeping ambient humidity down around 50-55%). You can see when the lights go out the temperature drops by about 5f degrees and that pushes the RH up (lower temp same humidity = higher RH). Also, the fan is sensor controlled so if it is above 78f or 60% humidity the fan goes on to help control the situation. I have lows programmed too, but they won't be needed until winter or maybe not at all. Day 25: As we move to week 4, I've been spending time learning and adjusting and remediating the grow on these 4 plants; 2x Northern Lights Auto, 1x Tangerine Dream Auto, 1x Blueberry. After too heavy a water on Day 20 (5 days ago!). They're still a bit damp at the roots close in, and I'm guessing that some root compaction along with my seed starter mix maybe being too heavy is to blame. -The plants are all recovered from any water droop now. -They're continuing to lose their yellow and grow more vibrant green, their new growth is a nice vibrant color. -With the moving of my lights up to get a bit less PPFD and get my DLI to the mid 30's has been beneficial. They're starting to gain some height. -They'll only get water this week. Once we're back to a regular water schedule I'll alternate. Day 26: I did water a little bit. Not much but about 10 or 12 fluid oz. per plant. I'm coming back from overwatered, but it's been nearly a weeks so the soil was really dry, but I'd been holding out so the root core at the ball had more of a chance. It's off to the races for the Tangerine dream...it doesn't have any branching yet, but is either pre-flower or right on in. This whole grow has been a learning experience shake down for the next grow, so It's more about 'well THAT is...interesting..." than me expecting great yields. It's been a pretty serious learning experience with me doing a deep research dive with each new thing or stage. Day 27: Having resigned this to the category of 'learning experience'...I'm fairly OK with these guys remaining small, though overnight they've gained. The largest is about 6" and the smallest is about 4.5" at this time. They've now stretched enough that light can get 'in the middle' pretty well and those nodes are starting to expand a bit outward. The new watering technique is working well, though the front right Northern Lights I suspect will have all the lower growth remain yellowed. The rest are looking better. The TD is in pre-flower but the others are holding their own...I hope they DO experience some growth that makes the flowering process fun to watch at the very least. Things remain hot/humid here the grow tent is sitting in the mid-to-low 80's in the day with a humidity that's sitting in the higher side of the 50% range. Day 28: A front ran through and it's cooler and dry again (73, 50%RH outside). Grow tent is sitting at ~80 until the cool air can circulate the house a bit. Got in and gave a bit of an inspection, cleaned the saucers, etc. As the Tangerweenie is in pre-flower and the other lil' ladies look to be headed in that direction, I adjusted the lighting to be reading around ~52DLI at the tops of the plants and closer to ~42DLI in the lower portions. Took a few moments to spread out the tips to let light in below on the plants which will be as close as I get to LST this round. Watered the plants with our usual tap (softened well water), which was reading 7.05pH from the source. I dropped that to 6.56pH and gave 'em all about 2-2.5 cups. The last feed was 2 days ago, so that seems reasonable. Next round I'll move to FoxFarms Ocean Forest and amend the soil more aggressively. Right now I'm using the Black Gold Organic which got 3c of pearlite & 2c of vermiculite per pot...its what I had on hand. Day 29: Sunday, making it a full 5 weeks since seeds hit soil. Yesterday's watering had no ill effect on the plants. No drooping, and the soil feels like it'll be good for another watering tomorrow. Yesterday I bent the branches out on the left and right of the two plants (Blueberry & 1 of the NL) that have multiple tops and have branched sufficiently. Of course they grew back vertical, so today I took a quick 5 minutes and wired them in place to open them up a bit. Very low stress and I'd expect no real ill reaction to it. Temperatures/humidity have reduced really nicely...it's 67f outside (10am) and 60%RH. Last night it hit the mid 50's outside. In the tent it dropped to 75f at night and is now riding at 76-79f and 49RH. Day 30: Nothing exciting to report. I did water again, this time with very light nutrients basically half of a half of the recommended amounts for week 4. Upped the water by about 1/3 of what I'd been doing. So, somewhere around 3.5 cups of water per plant. Did some rearranging in the tent and added a few more hang bars along the way. Day 31: Last day of Week 4. Upgrade to the tent: Terrabloom 6x16" carbon filter installed. Plants all have a bit of droop from yesterday's watering though I'm convinced that the soil is just holding too much water. I mistakenly used both Perlite and Vermiculite and the Vermiculite was the wrong move since it holds water. Next time I'd double or triple the perlite and leave it at that. That ol' learning curve in action.
