I needed a bigger reservoir, runoff catchment, and dehumidifier drain bucket because I had to go out of town for 5 days. Fortunately I calculated the volumes accurately and so when I got home I had at least another 24 hours of solution in the rez, and space in the runoff and dehumidifier catchment buckets.
The other fortunate thing is that I came home to very happy and vigorously growing plants. The tallest colas are now 30 inches above the coco, and 20 inches from the light. There is one cola (pictured) whose stem is as thick as a sharpie!
I ran out of the AN base nutrients and decided to switch over to GHE because the PH perfect buffers in the Advanced Nutrients line have been a huge pain in the ass. Also, I decided to mix my own bloom booster from Potassium Sulphate (0-0-53), Monopotassium Phosphate (0-52-34), and Epsom Salt after finding a DIY recipe (https://www.thcfarmer.com/threads/diy-hammerhead-confusions.47992/) to achieve a (0-9-18) NPK ratio. Significantly cheaper, but will be interesting to see what the results are in the end.
I will be doing one more heavy defoliation on day 21 of flower because there are so many fan leaves laying on top of each other that its hard to keep the humidity down. Stay tuned!

Grow Questions
MediciGradestarted grow question 5 years ago
The leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.

Shagrathanswered grow question 5 years ago
From my experience that leaf edge curling upwards means wrong VPD (temp/humidity ratio)
So you have too high temps or too low humidity for this setup and changing either one should correct this.
Can be also some other stress but usually its the vpd
MediciGradestarted grow question 4 years ago
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

everyone says 5.5-6.0, but unless your fertilizer says so, you should more likely stick to 6-6.5.
MediciGradestarted grow question 4 years ago
As you can see, one of my plants is a few inches taller than the others. They've all been topped 3 times for 8 mains, but I'm wondering whether I should top the big plant 1 more time in an effort to achieve a more uniform canopy height before flipping to 12-12.

What you can do to slow those tops down is to cut off the leaves just below the new growing tips, the one's that are already spread.. take one for minimal slowing or both for more.. it won't really shock the plant so much as slow it down a bit. Or you could just lst them out and tie them down or even just supercrop them by almost snapping them so they sag down they will heal back and be a bit more spread out! Cheers Happy growing!
MediciGradestarted grow question 4 years ago
I've been feeding 3 times/day at an EC = 1300 and PH = 6.2. Runoff this morning was ~700 on average. The plants appear to be happy but I'm worried that I'm underfeeding them and its slowing down growth. Should I increase EC? Should I start feeding more often?

The plants look happy, so if you make changes, make them slowly. Your run-off EC being that much lower than your inflow is kind of weird. A walk up of EC by maybe 50 or 100 points every few days shouldn't be too harmful - but be ready to back down at the first sign of leaf edges crisping.
The difference between them from week 8 to 9 is just marvelous!
MediciGradestarted grow question 4 years ago
I’ve read a lot of conflicting opinions these last few days regarding defoliation/plucking/pruning. Today is day 21 of 12/12 and my only goal is to prevent white powdery mildew. How many leaves would you take off?
RH overnight spikes into the high 70’s if the dehumidifier is off

Привет, бро! 👋 Я бы снял с нижнего этажа все большие развитые листья, со второго этажа я снял бы половину от имеющихся развитых листьев, этаж верхний с соцветиями я бы не рекомендовал дефолиировать! В общем я представил около 30-50 больших веерных листьев, но совсем оставлять лысой - не стоит! 👌 От души! 😇 Удачи! 👍

Weird growth. Are these nanners? What’s this seed looking thing? What should I do?

Nor_Cal_Kannablissanswered grow question 4 years ago
Yes sir.. sure looks like it.. Banana protrusions are unpredictable, and it can appear even in the most ideal settings. Sadly, it could also start fertilizing females. A few nanners would not cause much damage. However, if there are plenty, consider an early harvest to cut losses and prevent the flowers from forming seeds. You could try plucking the one's you see but you also run the risk of spreading it more. If it's just one plant I'd suggest removing it from the others if possible.. 👊

@BloodSweatBeers, big time. 5 months of care and attention only to wind up with 2 of the 5 plants go hermie on the home stretch. Learning experience though. Won't be messing around with anything but proven top shelf genetics from now on.

@grzesiekkuzniak, thank you sir. Have been finding a few seeds here and there from the 2 nanners I found last week. So I've decided to start the flush as soon as the solution I currently have in the reservoir has been depleted. l'll be harvesting a bit earlier than I had hoped but better than letting the problem spread. Cheers.

For your nutes was that for every water? Or did you occasionally use just water

@BloodSweatBeers, I feed 5 times every day at the nutrient ratios and EC levels noted. If you want to learn about the science behind high frequency fertigation this is a great resource: https://www.cocoforcannabis.com/principles-fertigation-feed-water-cannabis-coco/
