Blacksin01 Mother is in the back right. 4 week veg for all the plants (mother is closer to 8-10 weeks lol). These have all been trimmed and cut back probably 3 times. The growth is rapid. Got a slight tip burn from running the ec to high (1.5). Moved it down to 1.2 and the problem corrected. These are all getting foliar treated with Triacantonal (.01 ppm), Brassinolide (5ppm), and a root drench of Sodium NitroPhenolate-3 (50ppm). I will bump the triacantonal up to 15ppm this week and spray it once a week until week 3 of flower with brassinolide. I treated with the Sodium NitroPhenolate-3 two weeks ago, I’ll treat it again in 1-2 weeks and discontinue after that. My goal is to hit it hard during the stretch and flower set and then let it mature. I’ll only treat with brassinolide after that if I notice any major stress and need to adjust. 9 feeding events. 10s shot at lights up, then 7s shots for the consecutive hours after that. This is all drain to waste. My runoff ec and ph mostly matches input (slight ph up drift). The reservoir is being treated with .5ppm of calcium hypochlorite. Rockwool cubes do have algae growing but they get an occasional mist of hydrogen peroxide and hypoclorous acid.

Blacksin01 Did some defoliation this week and followed it up with a floral Brassinolide treatment to help the plants handle the stress. Gave them a floral dose of Triacontanol at 15ppm. I’m holding off one more week on the Sodium NitroPhenolate-3 until the flower sites start showing up, that’s when I want to hit it. Bumped nutrients up to full-strength Jacks: - 3.6 g/gal Part A - 2.4 g/gal Calcium Nitrate - 1.1 g/gal Epsom Salt EC went from 1.2 up to 1.7. I’m considering adding a bloom booster next week and pushing EC to around 2.0–2.1. I’ve got an old bottle of Big Bud lying around, but I’m cautious about burn. If they handle 1.7 well, I’ll test it out. *update* added big bud 2ml/l. Only added .1 to the ec. It must have something organic in it because my res got stinky a day after that. Had to hit it with calcium hypochlorite to knock whatever was growing down. Also fed sodium nitrophenelate at 50ppm, and did the weekly 15ppm triacantonal foliar treatment. Tomorrow I’ll feed brassinolide. Switched the irrigation over to the Athena precision schedule—7-second shots every 30 minutes starting an hour after lights on. After six events, it moves to three 10-second shots until an hour before lights off. The goal is to get some dry backs and a couple of light flushes before the end of the cycle each day. Running a dehumidifier during lights off to keep VPD elevated. Without it, humidity peaks around 70–75%, but with it, I’m holding about 60%. VPD sits around 1.2 lights off and stays steady at 1.2 lights on, right where I want it. Overall, growth looks great. The defoliation really opened things up for better airflow and lets the plants put more energy into the top nodes.
