Week 6 went by with a lot of bud bulking, all branches put on a lot of weight and start to struggle with carrying the whole load. I fixed them together with gardening wire and stabilized the canopy by putting holding wires up to the ceilings poles. Seems to work for now, but Ill have a close eye on those branches, that are pretty tight together to mitigate budrot.
Weather outside is quite rainy and moist, so Im struggeling to match the 50-60% humidity window for bulking phase. Dehumidifier doesnt keep up to the transpirational potential of the plants, so I just use it when inside temps are high and theres a lot of relative humidity (thats when it works most efficiently). In milder cases I just try to ventilate the room accordingly.
For the last 3 weeks I am going to dim the lights to around 1000PPFD which equals 75% (roughly) in my setup, starting with the first day of week 7. For the last 2 weeks I will also start to shorten the daycylce a few minutes every day to simulate late fall lighting conditions and promote maturing of the buds.
I stepped the nutrient solution concentration down to 2.0 since the substrate sensor registers really high EC values. So thats when I found out, Autopots work with high EC but you wont be able to get the salts out of there without flushing or draining to waste. Only dilution takes out some of the equation, as well as what the plants are uptaking. Which in turn leads to a skewed nutrient formula in the substrate solution.
Since we are in week 7 right now, the nutrient uptake by the plants lowered significantly, mirroring in the rising pore water EC value. Week 7 will continue with a 2.0 input EC, week 8 and 9 will be water only. followed by an increased dryback period before harvest. I plan to harvest on day 63 as that is what this pheno took last time. This run however, the plants are budding up quite a lot more and show quite a lot of new facets regarding bud size, weight and structure.
To this point, no real fading of colors into autumn mode is visible with exception of some tiny purple spots on some of the colas. Last run quite a lot of leave purpleing happened in weeks 6 to 9 of flower, which I now suspect the soil didnt provide enough phosphate turning some of the leaves purple-ish. Frost is pretty dense already, some colas look like they were dipped in powdered sugar.
Could you put your blower on top of your tent to make more room? Anyway your plants looks very VERY nice! 🔥 that going to be a massive yield! 😎 cant wait to try autopot on my next run. How long did you veg those babies?
@Smalltentgrower, Thanks mate! Yeah that would be the only option left without letting the scissors dance around the tops...would love to avoid that LOL. Since I have no free time available to tackle the exhaust repositioning this weekend Ill probably look into that afterwards, but i will need more piping to do that too. Maybe Ill just take advantage of the situation and realize air transport out of the room. Right now it goes into the room itself...
I tghinned them out quite heavily yesterday, but still massive plants :) Veg time is difficult to say. Took the cuttings when i flipped the previous run into flower and rested them near a window. By week 4 of flower I repotted them and started to give them light to pre-veg to size, before flipping them the night after taking out the previous, dried harvest. No time wasted sir 😎
