That a wrap for week 7. I gave the ladies one feeding with Flower 2(PK fertilizer) from Blue Sky Organics mid week. I hadn't planned on it but they looked a little hungry and they still have a little over 2 weeks to go.
They are showing some signs of stress (red striping on the stalks). This is likely for one of two reasons or both.... my room temps ran a little higher than normal as the weather here changed and warmed up a fair bit. That coupled with the added heat from the dehumidifier running regularly now as apposed to intermittently as needed in an effort to bring my humidity down to that 41%-43% range to close out the run. I like to slowly start bringing my humidity down in the closing weeks of flower so the plants uptake more water and nutrients. It also couldve been the distance from my lights to the plants. As I'm running new LEDs I've been playing around with different heights from the canopy to try and find that sweet spot where the plants are getting the most light possible without stressing them out. I cant confidently say with any amount of certainty that it's either room temps or lighting so in an effort to resolve the issue I raised the lights up to 19"-20" above the canopy and adjusted my intake/exhaust fans to get the temps down to 26.5-27.5 degrees Celcius.
As mentioned earlier in my diary the Terps in here are very strong and very fuel/gas dominant. It may be hard to see in the pics but the trichome production is ridiculous. I have to glove up just to move shoots around during health checks so I can see into the interior of the plants. When I did my last pruning on these ladies around day 40 I actually had to stop and soak my bonsai scissors after each plant. They got so caked just removing fans leaves that they literally wouldnt function.
I'll start checking trichomes in the next few days to see where they're at. I'll post pics in next weeks update.
@CRiSPrGrow, no I'm not measuring VPD. For seedlings and clones I run 24 hrs on for the lights at 60%-65% and 28 celcius. Veg I run 18/6 at 50%-55% and 28-29 celcius for lights on/26-27 celcius for lights off. First week of flower I run 25-26 lights on at 50%-55%. After first week of flower I try to stay in the 45%-50%. Last two weeks of flower I bring my hum down as close to 40% as possible. I dont bring down temps for late flower.
@Horticulturehobbyists,add the flowering week numbers to the veg week so instead of "flowering week 1" say "week 12 (flowering) " that should fix it, there's an edit button for the week where it should be easy to do... anyway wasnt dropping by about that lol , loving the sprouts tea... by the way are you measuring VPD too ?
Love the details. I’ll ask the question in this week, but I’m really thinking in the end of the vegetative state, for a light mix of various amendment and soil how long does a plant take to use up the nutrients? The rate at which a plant can access amendment compared to liquid plant food is clear, but I’m still not clear on how long it would take a plant to use up the mixed in food in a large final pot. Lets say I’m generally mixing 3 parts soil to 1 part various amendment in a final pot, am I looking at approx. 1-2 weeks of food, or a month’s worth of food? Any insights are appreciated.
Thanks Horticulturehobbyists, I’m learning alot in a short time with this journal.
@@BeanswithPork, it's hard to say exactly but from the time you top ammend the pots until the time the ecosystem you've built in the pot makes that food available to the plants is in that 7-10 day range. You feed the pot and the pot feeds the plant.
The red striping is something we've seen and we do a lot of Kush. Have generally gone with a touch of CalMag and time... but hard to say 'cause they always turn out :) This is a seriously crazy grow you've got.
