Captain_7 Plant growing well. Transplanted to 10 gal fabric bags day 30. Topped day 26, keeping 3rd & 4th nodes. Topped each branch keeping 1st & 3rd nodes. Growing to have 16 colas. Growing these organically, with a potting mix amended with various organic fertilizers (cricket frass, bone meal, composted chicken manure, alfalfa meal, kelp meal, gia green power bloom). Watered 1 gallon on day 34.

Captain_7 Plant structure is all set up, aiming for 16 colas in total. Adjusting the humidity down a bit, targeting a VPD of 1. Plants are healthy and growing well. Day 39, I added a thermometer / hygrometer sensor to monitor the conditions 24/7. The average lights on temp is 28.5, with a range from 28c to 29c two hours after lights on. RH range of 61% - 66% with an average of 63.1%. This gives a VPD of 1 which is right on target. Night temp drops to average of 21.8c, max 22c, min. 21.5c. I would prefer slightly warmer nights (22c average) but I will take this range for now. Watered day 41 with nutrient mix (PPM 100N - 90P - 100K). Day 42 - I removed some excess growth that was not getting direct light to help with airflow. Overall, very happy with this week's growth. I will put the screen in this week and let the plants veg for another 14 days.

Captain_7 Plan for this week is to get a VPD of 1.1, to get this I need a temp of 27.5 and a RH of 59%. I don't have much control over the temp as this fluctuates due to the exhaust fan and house temp, but I am able to keep this consistently between 27c and 28c with an average of 27.5c. Night temps also fluctuate but I am able to keep these between 21c and 22c, with a consistent average of 21.5c. I can control the RH quite well, with a +/- of about 1.5% on either side of the set value, it was slightly low but I corrected this and currently I'm averaging a RH of 59%.
I am increasing the light intensity to be 600 - 650 PPFD. Plants are doing very well starting this week. thinking two more weeks to the flip. plan to keep only the top bud sites and remove any lower branches. will be adding the netting soon, once they get some more height. I'm going to have to adjust my watering schedule as the humidity was too high for a couple days after watering. I will water one plant at a time and off-set the watering days.
My thought is that if I have all conditions dialed in, I will get a better sense for how my organic nutrient schedule is working.
Mid week update: The conditions seem to be in a very good. Temps and RH% are in the right range, I am really enjoying having the new sensor to track conditions 24/7. I watered 1 of the 4 plants in the tent and it didn't seem to have any impact on the humidity which is great. Overall things are great.
Day 49 update: my girl is looking great. trying to use the netting to spread her out a bit. Watered with nutrient mix, added some CalMg to the mix. The nutrient mix had a PPM of 718 this time around going in and I adjusted the pH to 5.8. Measured the run-off, the was ph 6.3, this is telling me everything in the root zone is where it should be. The run-off ppm was very high @ 3323 but I'm not at all concerned, as this is likely due to the fertilizer and worm castings that I mixed into the soil.
Overall, this week went very well. The girls are ready for the flip but I'll veg until day 58. The plants are healthy, responding well to the trimming I have been doing. There's no sign of any nutrient deficiency at all which is great. Im watering only once per week with 1 gallon of nutrient mix, as that seems to be how long it takes for the soil to dry out. Tent conditions have been on point throughout the week with a VPD of 1.1 on average.

Captain_7 Start of week 8 and things are looking great.
The plan for this week is to keep humidity around the 58%/59% mark, and the temp H:28 / L:22, with a VPD of 1.1 - 1.15. Light intensity will be around 600 - 625 ppfd. Height starting the week is 15".
I will be vegging for another 8 days and hope in this time the bud sites will be above the netting and spread out evenly. I plan to defoliate everything below the net to try keep energy going into the buds and not side branches, normally I let things get a bit more wild but not this time. The plants are getting nice and smelly now too.
I will be feeding the plants with each watering. By my calculations I'm feeding with a ppm of 100N - 50P - 100K - 150Ca - 30Mg with my three part organic fertilizer mix. So far this seems to be working but the real test will be in the flowering stage.
I'm still conflicted on whether the organic nutrient mix needs to be pH corrected. My current formula leaves a pH of around 4 when mixed. I've added baking soda to raise this to around 6 but I don't want to do this long term because of the salt in the baking soda. I've ordered pH up and will see how this works.
Part of me feels that with organic fertilizer, you are feeding the soil microbes (not the plant directly), who will then break this down into elemental form for the plants to use, with this I feel the pH of the feeding solution does not matter. On the other hand, I feel that putting an acidic mix in will lower the pH of the soilless mix and put strain on the soil to buffer the pH and bring it into a good range for the plant. Any thoughts on this topic are welcome.
I'll update as the week goes on with new pictures and comments.
Day 52: Im not too happy with the layout of the bud sites, the height is a bit uneven and some are being covered. I'll keep tucking under the net to improve this.
Conditions Report:
Day 49: Avg Hi/Lo: 27.7c / 22.19c ; RH% 62.1 / 60.4. VPD (lights on): 1.0 (RH high due to watering of one plant)
Day 50: Avg Hi/Lo: 27.7c / 22.42c ; RH% 59.1 / 63.9. VPD (lights on): 1.11
Day 51: Avg Hi/Lo: 28.15c / 22.45c ; RH% 59.23 / 58.5. VPD (lights on): 1.13
Day 52: Avg Hi/Lo: 27.6c / 22.35c ; RH% 60.04 / 59.5. VPD (lights on): 1.07 (adjusting set RH down to 56.9% to improve VPD)
Day 53: Avg Hi/Lo: 27.4c / 21.8c ; RH% 62.2 / 61.8. VPD (lights on): 0.97 (high humidity due to watering)
Day 58: Last day of 18/6
This concludes the veg stage of this grow. Im very happy with how everything has gone so far. the plants look healthy and the nutrient schedule seems to have done the trick. I will trim off excess growth below the netting soon to improve air flow and neaten things up a bit
Cheers!

Captain_7 First week of 12/12. The flip happened on day 59. Overall the plants look healthy going into the flowering stage. I'm going to be cleaning up under the netting soon. I'm expecting a 55 - 60 day flower. Plan is to continue with the organic fertilizer schedule. I'll be targeting the following ppm's for the flip (3 weeks): 150N - 100P - 150K - 130Ca - 28Mg. If things are not going well, I will use chemicals if necessary. I will continue to lower the humidity levels as the flowering progresses, and will try bring the max daytime temps to 26c. Currently the high is around 28c, so I will open up the venting a bit more to try bring the temps down. Lighting targets will be to get a DLI of 30, with ppfd of 700. Cheers!

Captain_7 Week 10 is underway and will be the first full week in flower and the plants are starting to stretch nicely. Overall they are in good condition, nice green foliage with no signs of any issues. I cleaned up the underside of the plant, removing any growth below the netting. I removed 4 of the branches that didn't make it all the way to the canopy. I'd rather remove these than have small buds to deal with at harvest time. I have not fed the plants with any nutrients in the last week, due to holidays and not having the time to do this. I will start hitting them with organic nutrients again on the next watering.I'm targeting a DLI of 30 for the early flowering stage, gradually increasing this to around 40 three weeks from the flip date.
On day 65, noticed some brown margins on some of the leaves. I raised the lights as it could be from too intense lighting. Will monitor to see if it progresses or not.
Week 10 is now complete. The brown margins are getting worse. I think it could be potassium deficiency as I have not fed the plants in a while. I will give them some fresh nutrients and fortify with some potassium silicate (not organic) to try remedy this quickly.
