FLOWERING WEEK 6 (Dec 15-21) ------------------------------------------------------ TARGETS: EC: 2.2-2.4 (IN) pH: 6.3 (IN) TEMP: 25c (DAY) 19c (NIGHT) HUMIDITY: 50-60% VPD: 1.0-1.5 KpA - Discontinue Silica - Reduce CalMag by half Very crucial week here. Generally after week 6 buds don't gain a lot of mass unless they're 9+ week strains. I really have no idea how long the flowering cycle is on these so I'm treading carefully. I'd like to be at peak nutrient strength right now but I don't want to cause any lockout from overfeeding. Runoffs we're getting high and pH was dropping below 6.2. The mix is a bit tricky here because the feed schedule says to stop CaIMag at week 6. That's likely assuming an 8 week flower cycle, but again, I don't know the cycle yet. For now I'm reducing the CalMag supplement by half to satisfy cation exchange in the coco. I've just removed Silica from the feed schedule after learning you shouldn't use it past week 3 of bloom 😆. That supplement was a massive boost to the solution pH, which is now missing and making if difficult to reach the target of 6.3. I'll have to run out and grab pH UP for the first time ever. Solution EC target of 2.4 is difficult to achieve without exceeding Remo's recommended element ratio as well. Still out of VeloKelp and I ran out of PK 14/15 so buying a few new bottles is inevitable. Shit looks good though. The Wild Runtz stash seed is exceeding expectations in a 3 gallon pot. The long colas on strong branching are starting to fill in with white pistils still sticking up. Kingpin is about as wide as it is tall (40"). The top 10-12" is bulking up really nicely. I'll have to start tying outside branches to each other to avoid any snapping later on but she looks sturdy. Pulling a few leaves out of the middle to get more light and airflow through her might be good. At the same time, I haven't done a lot of defoliation in bloom (fan leaves help keep humidity up through healthy transpiration) and the environment has been on target so I don't want to fuck with them too much. Dec 15 ------------ - Watered @ 2.4 EC / 6.2 pH (2:15 AM) (2L) - Runoffs: 2.8 EC ⬇️ - Watered @ 1.7 EC / 6.1 pH (5:45 AM) (6L) - Runoffs: 2.1 EC ✅ / 6.0 pH ⬆️ - Watered @ 1.9 EC / 6.2 pH (8:30 PM) (5L) - Runoffs: 2.3-2.4 Dec 16 ------------ - Watered @ 1.9 EC / 6.2 pH (5:30 AM) (4L) - Runoffs: 2.4 EC - Watered @ 2.2 EC / 6.3 pH (7:30 PM) (6L) (VeloKelp back) - Runoffs: 2.4-2.5 EC / 6.0-6.1 pH Dec 17 ------------ I took a trip to the grow shop and they had VeloKelp back in stock (didn't call me) so I grabbed another litre. Also picked up a small bottle of Sensizym and the pH UP. Totally forgot about the root cleaner up to this point. I'll only run this for two weeks before discontinuing. - Watered @ 2.3 EC / 6.3 pH (1:00 AM) (4L) (+Sensizym) - Runoffs: 2.5-2.6 EC - Watered @ 2.4 EC / 6.3 pH (5:30 AM) (4L) (+Sensizym) - Runoffs: 2.8 EC / 6.1 pH - Watered @ 2.4 EC / 6.4 pH (8:30 PM) (6L) (+Sensizym) - Runoffs: 2.6-2.8 EC ⬇️ / 6.1 pH (3.1 EC after 4L) Dialing back the EC. Doesn't seem sustainable with the amount of solution I'm dumping in to maintain the root zone EC. Getting a ton of runoff and that means waste. I'll drop back to 1.8-2.0 EC tomorrow and see where it's at. Dec 18 ------------ - Watered @ 1.8 EC / 6.4 pH (1:00 AM) (3L)⬆️ - Runoffs: 2.7-2.8 EC ⬇️ - Watered @ 2.0 EC / 6.4 pH (5:45 AM) (6L) - Runoffs: 2.3-2.4 EC - Watered @ 2.1 EC / 6.5 pH (7:45 PM) (4L) - Runoffs: 2.5 EC / 6.1 pH Dec 19 ------------ - Watered @ 2.2 EC / 6.3 pH (5:45 AM) (4L)
