It is the end of flush week and she went into darkness on Wednesday night, day 75, for two days. Saturday will be harvest day and start and the dry process👍
She has certainly been going through the beautiful stage of senescence and her fade is gorgeous. The purples and yellows coming out are great......covers up the brown spots😂😂 Her buds are densing this week as we work on bring down the humidity. Running in the mid 60’s for humidity late in flower is a different experience and one that takes some getting used to. Bring down further to low 50’s has really helped to bring out her frost as well. Kept the humidity high to form big buds......now lowering to make them more sticky👍👍
I am feeling very strongly that the big part of the pH issues this run was a change in feed water. I have always used bottled RO water for all my grows, except outdoors, but this grow I switched to tap water. Dechlorinated the water with air stone and gave it 24 hours min before using. Wanted to save some money and tired of lugging bottles downstairs a couple of times a week☹️ This is worked out nicely and a lot more convenient. However, the city must be putting some crap in the water that is causing issues in my media and raises the pH after the watering. Out of the tap it is 8.4pH and 275ppm. Since ppm were not too bad in my opinion I moved forward without filtering the water.......oops🤬🤬🤬 Out of options on what is causing the issue, I switched back to RO water late last week........all the girls are happier!!!! F......missed the cause for weeks. Always learning from this plant and my own mistakes to get better every run😉👍
Also wanted to add a little more stress to girl to help push out some increased resin. I drilled a 5/16” hole into the main stem to cause her stress. I did this rather than trying to break a branch and will see how it goes this run. Sterilized a new bit in Alcohol and went for it. They went into darkness about a couple of hours later. Excited to see what happens when she comes out to get chopped😃😃
Little more detail......
June 20/20 - Day 71
- Rezin and Liquid Weight @ 2ml/L = 285ppm and 4.0ph
- 8L given to get a good flush
- Runoff in pots already were 7.8pH and 485ppm.
- after 8L water runoff was 7.0pH and 370ppm.
- she is 29” tall and 30” wide.
- tricombs still mainly cloudy.....review again in couple of days.
June 21/20 - Day 72
- Dry out day
- buds are firming up......squeezed a couple🧐
- temps are nice outside so tent able to hold 75 degrees and 51% humidity.
June 22/20 - Day 73
- Rezin @ 1ml/L = 120ppm and pH the water to 2.7!!!!!!!!!
- Given 2L watering.
- No runoff water and I am good with that as I want the low pH water to stay in the medium.
- She will be ready soon. Thinking darkness on Wednesday and harvest on Saturday??
June 23/20 - Day 74
- 2L plain water feed - 80ppm and pH to 2.4!!!!!!
- not excited about these crazy low pH numbers but doing what we can
- her tops are getting really pointy now and her leaves are very yellow.
- checking tricombs, I think we are done and tomorrow will be her last day so that I can take down on Saturday.
June 24/20 - Day 75
- 2L plain water feed - 80ppm and pH to 3.0
- Going into darkness tonight so this was her last bit of moisture.
- drilled a hole into the stem.....was going to do a couple of holes but not trying this method before I decided to leave it with one hole.
- into darkness tonight
So we finish up the week with her in the dark. Next update will be the harvest!!
Thanks very much for taking the time to review my diary!! Sorry for running behind often on this run.........everyone has had a busy life the last couple of months in the world and its been no different here...........a huge Kudos to all the Growmie‘s that are able to keep up with their diaries on daily basis on GrowDiaries.......its a commitment😃👍👍
Mephisto has bread a very nice girl. She is big and sticky and grown very well considering the environment she has been given. Battling the high pH and still turning out as she has is awesome and much respect!!!! Great job Mephisto, can’t wait to run her again.......just so happens I have several more seeds of her😃👍
@Med_in_Tropic,Hello Med!!!! Thanks for the message.....that means a lot to see a friendly comment :) There has certainly been lots of distraction around here so its nice to get back to some time with the community and our beautiful girls:)
I see you have been as busy as always with your many projects the last month! It will take some time to get caught up again :)
Cheers Med and hope Mother Nature is spreading the love on your girls!
Great to see someone else tracking VPD. It's tough to get a handle on. What tool are you using to calculate VPD? I have one calculator on my Android phone and a couple of Excel spreadsheets that I use. I've now managed and tracked it essentially through the entire lifecycle.
The recommended ranges that I've seen are as follows:
Propagation/Early Vegetative Growth - Low Transpiration: 0.4-0.8
Late Veg/Early Flower - Healthy Transpiration: 0.8-1.2
Mid/Late Flower - High Transpiration: 1.2-1.6
With an air temp of 79F and assuming a leaf temperature of 77F then you would need to raise the RH to 75% to get to a VPD of 0.63.
Getting a stable VPD is tough. I use an external thermometer and humidity gauge. That gives me a glance at the conditions before opening the grow space or tent. Just opening the door changes everything for a bit. I use a regular "laser thermometer" to measure the leaf temp. I just average the readings in my head, nothing special. What is your process for measuring the factors and calculating VPD?
Good luck with the grow. She young with plenty of time to recover.
@PrairieFrostGrow, more than "guessing" a humidity range, I really urge you to get a laser thermometer (like this one on Amazon: https://amzn.to/3ggGNGF. Not recommending this one, just an example.) This will really let you calculate the VPD.
I haven't slept well for a number of weeks, so I found myself checking the plants nearly around the clock. I too noticed how humidity spikes during the dark cycle, but I didn't worry about it! That's exactly what happens in nature. Sun goes down, humidity comes up. Once you are happy with the daytime results, then you might want to consider doing something different in the dark. Also, you might go to 20/4 schedule. It works well with and you have a shorter dark period.
Good luck 🍀🌠with the grow.
@BladeCutter,Thanks for dropping the comment Bud. Keeping an eye on VPD this run but also just learning more about the high humidity and how my environment reacts to it. Have found that pulling the humidity back down in the evenings a challenge with running it so high for 18 hours of the day.
I really noticed how in Veg they loved the humidity at the 70% range........hitting that 1.0kpa range and the leaves were up and perky!
Keeping an eye on them through Flower and see how they react to the 60 to 65% range.......again, I am finding it tough to bring humidity back down the 40% range for 6 hours while they are sleeping and transpiring. Have a dehumidifier and working with the settings to dial it in for a better understanding next run. Controllers are a must for temp and humidity when trying to keep the VPD dialed in.........I should have invested in ones that allow you set a different daytime vs nighttime numbers though as I change the settings manually twice a day everyday.
Cheers Growmie and thanks again!!
I have a SnS at day 10 and she looks like the mirror image of yours at this stage. I too was wondering if I was heavy handed with something because she does not seem to be as lively as the other plants I have growing.
@PrairieFrostGrow, she is looking great. I am a bit concerned as I just fed her epsom salts for the first time yesterday. I will monitor for signs of any issues. Otherwise this is one resilient plant. She took some abuse with my heavy handed LST and even being dumped on her head. You are absolutely right, a lot to be learned from this grow. Thank you for the update. Looking forward to more.
@Shielded77,my issues have been around pH personally. Narrowed it down to either an early feed with too much Epsom Salts and/or cheap fabric pots. Flushed her fairly hard early on and she is coming back now. This pheno seems to have taken the high pH well. Hovering around 7.1 in coco and just couldn't bring it down slowly........lost a week and a half in veg and then finally flushed her.
See you have not been without your challenges either........good luck on the rest of the grow and by not culling her you will continue to learn more about this awesome plant:) Cheers growmie!!
Hello from Russia. Your Plants look great! keep developing in the same spirit! If you are interested in following the adventures of weed in Russia, then subscribe to my diaries
@JinksyGrows, @ PrairieFrostGrow
Thanks for you kind comments bro’s.
You guys are giving me too much credits. Although I appreciate the camaraderie.
Happy gardening!
@JinksyGrows,Hey Jinks......Thanks Bud!!! Still have not opened up the tent yet today to see how they did in the darkness. I stole the hole idea from @Med_in_Tropic because I loved his fork idea from one of his last runs.......love it Med!!
Cheers Growmie.......your visits are always appreciated!
@Momgrowsthechronic, thanks for the comment! As a matter of fact I am.........won’t see too many outdoor diaries from me☹️
Your run is looking awesome....nice clean, tight setup!
Cheers!!
Thanks @toyahgerool, I have had good luck with frost level on plants from Mephisto! I wish an home grower could take a sample in for testing somewhere that is discrete and cheap😞 maybe one day😇
I freaking love your stuffy Bud!!!!!!!!
👌Nice harvest! Got a plant now which is exactly the same height, but at week 8, and grows similarly when it comes to the timeline. Hope to finish with the yield at least a bit close to yours. Great job!
